Retrobrighting with Just the Sun!

Retrobrighting with Just the Sun

Came across this idea of retrobrighting with just the sun on YouTube. I was highly sceptical so thought I’d give it a go myself! It’s a pretty simple idea. Instead of slathering your yellowed computer in peroxide, or immersing it in bath of bleach, simply stick it out in the sun for a few days! Sounds too good to be true right?

Enter the VIC

My VIC20 had some pretty unpleasant yellowing to it so I used that as my test subject. For 4 days straight I put it outside on a south-facing bench in the garden. I’d place it there before I left for work in the morning and bring it in once I got home in the evening. Today was the 4th and final day.

I’ll let the results below do the talking. I used the same white cotton bud in each photo as a frame of reference to judge the level of yellowing. I also took the photos in the exact same location at the same time of day to keep the lighting as similar as possible. No flash was used in any of the photos.

Before & After Results

I’m extremely pleased with the results. The overall yellowing has vanished, even the quite pronounced yellowing around the grill area has gone too. The beauty of this method is that I literally did nothing – the sun did all the work for me. I didn’t even need to dismantle the computer!

Conclusion

I’ve had some disastrous results using peroxide gel in the past. On one occasion I ended up with an appalling marbling effect on a rare C128D keyboard. After that incident I had vowed never to try my hand at retrobrighting again, however this test has changed my mind. It looks like it’s the safest and easiest way imaginable to brighten up yellowed plastic. It’ll be interesting to see if the brightening effect lasts. If the yellowing comes back in future I’ll update this article.

Modding Amiga 500 Floppy LED to Display IDE Activity

Introduction

Unlike the Amiga 1200, the A500 was never designed to allow the fitment of an IDE Hard Disk Drive (HDD) inside it so naturally it never included an HDD activity LED. For the longest time this was never really an issue. Sidecar expansions such as the A590 were the only way to add HDD’s to the A500 and they came with their own drive activity LED. However, now that many owners are fitting expansions like the Vampire into their Amiga 500, things are a little different. These new devices facilitate the use of 2.5″ HDD’s or Compact Flash (CF) cards inside the casing of the A500, something that was never possible before.

The problem with this is the lack of a drive activity light. It can be quite disconcerting at times when you turn on your ‘Vampired’ Amiga 500 and nothing appears to happen. You sometimes wonder if it’s actually booting up or simply frozen. The same issue crops up whilst loading a game or running a program. There’s simply no way to tell if your Amiga is doing anything, especially if you’re using a CF card as they are completely silent. At least if you have a 2.5″ HDD they do at least make some sounds whilst being accessed.

Wouldn’t it be great if you could add a hardware activity light to your A500 to solve this issue? Well, recently I stumbled across a nifty little mod from Arananet that claimed to allow you to do just that by using the Amiga 500 floppy disk activity LED to show IDE HDD/CF activity. It’s called the ‘IDELED’ and is only €7 plus postage so I ordered one and sat back waiting for it to arrive.

Incidentally, if you fancy making this modification yourself all you need is a phillips screwdriver (to open the A500 case up), some wire cutters/strippers and a soldering iron. Don’t worry if you’re not an expert solderer, I’m rubbish at soldering but this is very basic stuff and should be well within most peoples capabilities.

A closer look at the IDELED device

The device arrived in a little anti-static bag with no instructions. It’s a tiny little 1″ square circuit board that incorporates an 8 pin socket one one side and 8 pins on the other. There is also a small hole for you to solder a wire to, plus a few components that allow it to ‘do its thing’.

This slideshow requires JavaScript.

Getting Started

The IDELED is designed to sit between the Amiga 500’s keyboard connector and the keyboard cable. This gives it access to the floppy drive LED circuit and allows that to be used as an IDE activity LED in your Amiga 500. After opening up your A500 the first thing you need to do is carefully unplug the keyboard connector, lift away the keyboard and set it to one side.

Unplug the keyboard connector (circled in red).

 

You’ll then have access to the 8 pin keyboard connector on the mainboard which will look like this:

 

Amiga 500 keyboard connector pins

Keyboard connector pins

 

Next you need to attach the IDELED board to the keyboard connector pins on the mainboard. Make sure that you connect it the correct way around – orient the board so that the keyboard connector is at the back if you are looking at it from the front of your Amiga. It should then look like this:

 

IDELED board

IDELED fitted to keyboard connector

 

At this point I connected the keyboard to the pins on top of the IDELED board. You might want to leave doing this until after you’ve soldered the connecting wire but I needed to experiment a bit and wanted the A500 powered on and the LED’s working. At this stage the project looked like this:

IDELED board fitted between mainboard and keyboard cable

 

Solder time

The next job is to attach a short wire to that little solder point on the left side of the IDELED board. The wire needs to be long enough to reach the IDE connector on top of your Vampire (or other accelerator card) with enough slack so that it’s never under any strain if you have to move things around in the future. You will need to strip off a few millimeters of insulation from each end of the wire before you go any further. It’s much easier to do this before one end of the wire is attached to anything. I’d also suggest ‘tinning’ the exposed wire each end as this makes soldering them easier.

Insert one stripped and tinned end of the wire into the little hole in the board and apply a blob of solder. You should now have something looking like this:

 

Amiga 500 IDELED board

IDELED board with ‘activity’ wire soldered on

 

Locating pin 1 and 39

The other end of the wire needs to go to ‘pin 39’ on your IDE adapter. This is the pin responsible for transmitting drive activity. If you have a CF adapter like mine (pictured below) then you should be OK to just hook the wire up to the same pin as I did.

Locations of pins 1 and 39 on my 44 pin IDE adapter

 

 

To locate ‘pin 39’ on my adapter I used the 44 PIN IDE connector diagram below for reference. Note the way the pins are numbered – it alternates up and down with 1 top left, 2 bottom left, 3 back to top row and so on. My particular adaptor has the upper row of 22 PINs connected to the top of the circuit board and the lower row of 22 pins to the underside.

2.5″ 44 PIN IDE pin layout & numbering

 

Provided it was connected up the correct way round originally, the purple edge of the ribbon cable indicates which side ‘pin 1’ should be. Thankfully the Vampire card clearly indicates where ‘pin 1’ is (see the little ‘1’ above the bats head in the photo above) so my cable was oriented correctly. Once I was sure of the location of ‘pin 1’ it was a simple matter of counting along to identify ‘pin 39’. Obviously if you have a different kind of adapter then you will have to confirm its location yourself. Hopefully the information above will help you out.

Wire soldered to pin 39 – not the prettiest soldering job in the world but it does the job.

View showing the completed modification in its’ entirety.

 

Assuming you’ve connected everything up correctly (check  before you screw the case back together), you should now how a fully working IDE activity LED on your A500.

 

Demonstration

In the video below you can see my Amiga 500’s new IDE activity LED flashing away whilst it boots into Workbench. The loud clicking sound is just my empty floppy drives clicking – the anti-click software doesn’t run until workbench has finished loading.

I’m really pleased with this mod, it was cheap, pretty simple to implement and above all else, really useful. No longer will I be in the dark about when my CF card is being accessed!

 

 

But wait, there’s more!

When you pop in a floppy disk the activity LED still flashes away as usual so there is no loss of functionality. Quite the opposite in fact as the LED even flashes when I use an SD card (the Vampire supports SD card storage too) which is totally awesome and something I definitely wasn’t expecting. An added bonus is that because Commodore simply labelled the A500’s floppy activity light as ‘Drive’ it’s still labelled correctly! How’s that for future-proofing!?

Anyway that about wraps this article up for now. I do hope you found this article both interesting and useful. If you did, please let me know by leaving a comment below, I’d love to hear from you.

Replacing Grotty Game Library Cases

Replacing Game Library Cases

Replacing your game library cases is a very quick and easy method of rejuvenating some of your old cassette games. If yours are anything like some of mine then you may have several scratched up, chipped, broken or yellowed cases skulking around in your collection. The good news is that there are still companies out there supplying replacement cassette library cases. The company I use, based in the UK, is called Tapeline but there are probably others too.

The ones I’m using here are just standard black library cases costing around 26p each at the time of writing. You can get a variety of different types and colours too, even double and triple cases should you need them.

Once the cases arrive it’s simply a matter of removing the cassette tape and paper ‘J’ card inlay from the old case and popping it inside a nice shiny new one. Here’s a few before and after photos to show the difference they can make. I’m sure you’ll agree that after replacing the game library cases the games look infinitely better, almost like new!

How to Format an SD Card for Amiga to PC File Transfer

SD Card Amiga PC Transfer

Introduction

The whole benefit, to me at least, of having an SD card reader on my Amiga 500 is to allow me to transfer files to and from a PC. In order to do this the SD card needs to be formatted in such a way as to be readable by both systems. Turns out it’s not too hard to do. This post will show you exactly how to achieve this and also serve as a reminder for myself in the future when I inevitably forget what I did!

 

Stuff You’ll Need

I used a MicroSD card for this task but the process would be the same for a regular full-size SD card too. I have personally got this working with a 32GB card and more recently with a 200GB MicroSD card! Please note that I have a Vampire Card in my Amiga (which has a MicroSD card slot) and use Apollo OS (Coffin R34 – Amiga OS 3.9). This solution is based on that scenario. If you want to find out more about my Vampire upgrade please read about it here and adding an SD card reader here.

 

By the way, this should work with most SD cards you may have lying around. However if you don’t have one or would like to know one which definitely works then here’s the exact 32GB MicroSD card I bought on Amazon.

 

Formatting the card on a PC

First things first – the card MUST be formatted on the PC, not the Amiga. The format we need to use is FAT32 as this is easily readable on the Amiga whilst still being compatible with the PC. The main disadvantage with FAT32 is it has a 4GB file size limit but this should never really be an issue with the Amiga as most of the files we will be dealing with are only a few MB in size.

I’m using Windows 10 which annoyingly doesn’t have a native FAT32 format option (only NTFS or exFAT). After searching around I settled on this free 3rd party FAT32Format app to get the job done. If you already have some FAT32 formatting software then by all means go ahead and use that. If not then this one is free and very simple to use, you don’t even need to install it, just run the executable.

  • Run the .exe file you just downloaded and make absolutely sure that the drive letter under ‘Drive’ matches that of your SD card.
  • Leave the ‘Allocation unit size’ at the default setting.
  • Give your card a name under the ‘Volume label’ heading but keep it short. No more than 11 characters and avoid using any symbols. In the example below I called mine ‘AMIGA SD’.
  • Ensure ‘Quick format’ is ticked (otherwise it’ll take forever) and then click ‘start’.
  • When the format warning box pops up click on ‘OK’.

View after the card has been formatted

 

A few moments later you should have a nicely formatted FAT32 SD card! As you can see from the image below it has been correctly formatted as FAT32 and shows approx 29GB of free space. It’s perfectly normal to lose some space when formatting disks so don’t worry that it doesn’t exactly match the capacity of your card.

Configuring the Amiga side of things

Now it’s time to take the SD card over to your Amiga for the next stage of the process. This is going to involve editing a DOSDriver on the Amiga with the parameters needed to successfully read and write to your SD card. Unless you’ve been messing around with SD Cards already there won’t be an SD0 device in your Amiga’s SYSTEM:DEVS/DOSDrivers directory. Fear not though because you can finding it lurking in the STORAGE directory (SYSTEM:Storage/DOSDrivers) waiting to be put to good use. Find the SD0 file and open it in your editor of choice, for me that’s the one built into Directory Opus. Edit the file so that the contents look exactly like the one in the image below:

 

SD Card Amiga PC Transfer

SD0 DOSDriver File contents (shown in Directory Opus Editor)

 

SD Card Amiga PC Transfer

Slightly clearer copy of the config (pasted into Wordworth to make it clearer to read)

 

Save your changes to SD0 and close the editor. This next part is particularly crucial otherwise, despite all your efforts thus far, the card will still be unreadable. You need to move the file OUT of SYSTEM:Storage/DOSDrivers and place it INTO the actual SYSTEM:DEVS/DOSDrivers directory. Doing this will force the Amiga to read the config on boot and enable it to recognise an SD card when present. You can do this in a number of different ways but again my preferred method is Directory Opus.

 

SD0 DOSDriver File Content

Edited SD0 correctly placed in DOSDrivers Directory

 

Once you’ve done this, assuming the card is already inserted, reboot your Amiga (CTRL-A-A) and when Workbench has loaded back up you should see a lovely SD card icon on the screen similar to the one below.

The next image shows a 200GB MicroSD card working and you can see the Amiga recognising the card capacity as 183.3G.

Here’s a regular 32GB card working recognised as being 29.1GB capacity. If you remember from earlier on that reported size is pretty much the same as how Windows saw it.

Useage

 

I find my Amiga/PC formatted SD card incredibly useful, not only for transferring files between systems but also for storing CD’s on. I don’t have a CD drive on my Amiga but I do on my PC. Any Amiga CD’s I get, such as the Amiga Future Coverdisks, I simply copy into a folder on the card and they’re instantly available on the Amiga. The 200GB card is particularly useful for this purpose as it can potentially hold nearly 300 CD’s plus all my other stuff.

 

I have noticed that SD cards work a little differently on the Amiga. You can’t just insert one and expect it to appear in Workbench. The card needs to be present in the card slot before you boot your Amiga up. Likewise, if you remove it, it will still show the icon on your Workbench. For these reasons I’d recommend always inserting the card whilst your Amiga is off and not removing the card until you’ve shut down your Amiga just to be safe. If I ever find a way around this I’ll update this post.

 

Anyway, I hope this post proves useful for a few people, I know it took me quite a lot of stumbling around before I brought all the parts of the puzzle together!

 

Network your Commodore 64

I’ve had my 1541 Ultimate II+ cart for around a year now. It’s a fantastic modern addition to my Commodore 64 and one that I certainly wouldn’t ever want to be without. However in all that time I’ve never bothered to explore using its built-in Ethernet port. Well the other day I finally got around to setting it up and am really glad I did too. I thought I’d share my experience in case it can help someone else get more out of their device. Basically this post will explain how to network your Commodore 64   (with a 1541 Ultimate II) to copy your games, music, demos, documents or anything else straight to your 1541 Ultimate II without ever needing to swap USB drives around.

 

Connecting to your network

You may have noticed the red ‘Link Down’ status that appears on screen when you press the menu button on your Ultimate cart. The is basically the built-in network card of the device telling you that it’s not connected to anything. The ‘MAC’ with the 12 Hexadecimal codes along side is the ‘MAC Address’ of your cart in case you need to find it on your network router.

 

Network your Commodore 64

‘Link Down’ Status shown in red

 

All you need to do to network your Commodore 64 is connect it to your router with an Ethernet cable. Providing your router is configured to use DHCP (and by default, pretty much all of them are) your cart should pick up an IP address on your network straight away.

 

Network your Commodore 64

Ethernet cable plugged in. Note the Green link/activity light. This should blink on and off.

 

After you have plugged the cable in you should see a green activity light appear on the device itself. You should also see an IP address appear on the menu screen and the red ‘Link Down’ status should change to a green ‘Link Up’.

FTP Software

So far so good, but it’s still not much use at the moment. To be useful you’re going to need some FTP software on your PC. I’ll use Filezilla as an example as it’s free and easy to use. The principal will be the same regardless of what software you choose to use. (As a side note I normally use Directory Opus which is still going strong – only just for PC’s these days rather than the Amiga). Note, if you are going to download and install Filezilla it’s just the client you want, not the server version. Also make sure you un-tick any boxes during the install to avoid any unwanted ‘bundled extras’ being installed (one of my pet peeves these days). The FTP software is going to allow you to connect to the USB storage device that is plugged in to the 1541 Ultimate II and transfer files across.

 

Network your Commodore 64

Configuring the FTP software to connect to your C64

 

Adding your C64 as a ‘site’

Once you’ve got your FTP software up and running you need to add a new ‘site’ to it (basically your 1541 Ultimate II). Simply got to the ‘File’ menu and select ‘Site Manager’ and then click on ‘New Site’. Give the site a suitable name so you’ll be able to recognise it easily in future. I simply called mine ‘C64’. Now make sure all the various settings below are entered. These have already been entered in the screenshot above.

 

  • Protocol: FTP
  • Host: (this will be the IP address displayed on YOUR C64 screen)
  • Port: (you can leave this blank)
  • Encryption: Only use plain FTP (insecure). (You are only transferring stuff within your own home network so this is not an issue)
  • Logon Type: Anonymous

 

Once you’ve checked that all the above settings are correct, click on ‘connect’. The new site you’ve just created will be saved and it should connect to your Ultimate cart and display something similar to the screenshot below.

 

Network your Commodore 64

FTP software – PC on the left, C64 on the right

 

The top window is basically a scrolling log of the actions performed by the FTP software and is just for info purposes. The two areas highlighted in blue and red above are where you can get stuff done. The left hand side is your PC and the right hand side your C64, or rather the USB drive plugged into your 1541 Ultimate II. The upper window on each side is where you can browse through the directories / folders whilst the lower section shows you the contents of them.

 

How to actually transfer games onto your C64!

To transfer games across to your C64 all you need to do is click through to where they are stored on your PC in the left window, where you want them to go in the right window, and then simply drag and drop them over, it’s that simple.

 

Network your Commodore 64

Files being transfer over FTP

 

In the above screenshot I’ve dragged a bunch of Rob Hubbard SID tunes across from my PC to my 1541 Ultimate II’s USB drive. You can see a log of what is happening in the top window and view the individual files’ transfer progress in the bottom window.

 

Network your Commodore 64

The files on my C64 after being transferred across

 

The file transfers are really fast, taking just a few seconds so I find this a really quick and convenient way of getting new software onto my C64 without constantly faffing about with a flash drive. I definitely won’t be unplugging that USB drive from my 1541 Ultimate anytime soon now!

 

Reservations

One other thing you should probably do is to ‘reserve’ your C64’s IP address on your router. Most routers offer the facility to do this. This will ensure that every time you turn your C64 on it will pick up the same IP. If you don’t, it will likely get a different one each time and you will need to change the connection info in the FTP software.

 

Apparently you can also connect to the 1541 Ultimate using Telnet and use it for stuff life swapping disk images on the fly for multi-disk games. I might explore this in the future but I doubt it would be something I’d use much, unlike transferring files across which I do on a regular basis. Anyway I hope this has helped you to network your Commodore 64. If you have any questions or comments please do get in touch.

Replacing the Drive Belt in an AIWA HS-PC202 Mk 3 Cassette Player

AIWA HS-PC202

Introduction

I recently bought a ‘New Old Stock’ AIWA HS-PC202 Mk 3 Personal Stereo off eBay as I just couldn’t resist the idea of unboxing a ‘new’ walkman in 2018. Now I’m fully aware that you can buy brand new ones off Amazon but these are pretty cheap and nasty affairs designed to cash in on nostalgia rather than offer a quality audio experience. This Aiwa model is a quality bit of kit with the ability to play Chrome tapes, Dolby B & C noise reduction, auto-reverse and a super slim, attractive design.

However it had been sat in storage for about 25 years so when I popped in some batteries and tried to play a tape – nothing happened! I could see the power LED light and hear a hiss from the headphones but the spindles didn’t turn. Thankfully I could hear the motor run momentarily if I held the unit to my ear whilst pressing ‘play’. This was a sure sign that the belt had failed in some way which is very common on vintage cassette decks.

This post will provide instructions on how to open up the AIWA HS-PC202 Mk 3 cassette player, and replace the belt. The only tools you need are some small watch-makers screwdrivers and a pair of tweezers. It’s quite a straightforward job as the player has been designed with the foresight that one day someone would need to change that belt!

Getting Started

The first thing you need to do is unclip the battery compartment as one of the screws you need to remove is hiding behind this. Now you need to remove the backplate from the player to expose the belt. It is held in place by 3 tiny screws and a clip that fits inside the case near the play button.

Take your philips screwdriver and remove the first screw shown in the picture below. Place it in safe place, preferably in a small container as the screw is incredibly small and easy to lose. This is a slightly different size to the next two so it should be easy to identify when you are putting things back together.

AIWA HS-PC202

Remove this screw first

Now spin the player around so you are looking at the side where the lid hinges and remove the two screws indicated in the photos below.

Removing the Backplate

Store these two screws safely with the other and put aside as you are ready to begin removing the backplate now. You need to be careful and not rush this next part as there are a few things that are held in place by the backplate and they will fall out and get lost if you’re not careful. The one thing seems to fall out no matter what you do is a small, circular, black plastic spacer that fits between the backplate and the DC power socket. Now you know about it, be prepared for this and catch it. Store it safely with the other screws.

The other things held in place by the backplate are the Dolby NR and Tape Bias selector slide switches. It’s simple to put them back if they fall out – but if you’re not expecting them to drop out they could easily fall on the floor un-noticed and get lost.

AIWA HS-PC202

This is the small plastic part that will fall out from around the DC power socket.

AIWA HS-PC202

These are the Bias and Dolby selector switches that may drop out when you remove the backplate.

The backplate needs to pivot away from the case from the battery end first. There is a lip at the opposite end by the volume wheel and switches so you need to picture it hinging from that position and focus your efforts on making it open that way. If you place the player vertically it’s easier to do this and it will prevent the switches from falling out.

AIWA HS-PC202

Gently prise the backplate off, starting at the battery end (the bottom in this photo)

As you can see in the above photo there is a small metal tab on the front edge of the backplate that fits into a plastic lug inside the case, above the play button. You will need to carefully slide a small flat bladed screwdriver in and gently lever the plastic around the play button outward, away from the backplate to release the tab. The backplate should now be free and you can pull it away from the body and slide it upward to remove it, leaving the switches on the top in place.

AIWA HS-PC202

The backplate – note screw holes and cut-outs for controls and DC input.

Inside the AIWA HS-PC202 Mk3

Now that the backplate if off you should see be able to see the circuit board with a cut-out for the belt and pulley wheels just like in the photo below. A belt in good condition should be taught and fit around all the pulleys tightly, something that mine was definitely not doing!

The smallest wheel is the motor pulley, the two large brass wheels drive the capstans and I think the smaller black wheel is there just to guide the belt around the others.

Replacing the Belt (Take 1)

It took quite a lot of investigative work to locate a new belt that was an exact match for the original. Avoid those cheap multi-packs you can pick up off Amazon and eBay from China – the quality of them is variable at best and the chances of getting one that actually fits correctly is next to zero.

The belt fitted to this walkman has a square cross-section, not round or flat like many other belts. It is also very thin – about 0.6mm thick. The length is 76mm. For belts most suppliers use the measurement of the diameter of the belt when laid out flat in a circle. So basically you need to find a 0.6mm x 76mm belt. I couldn’t find one this thin at first so I bought a 1mm x 76mm belt. It did fit and work but was quite a tight fit around the black wheel where it nearly touches the side of the case. It was also only a fraction of a mm away from touching itself (ooerr) where it passes beneath the nearby brass pulley (see the photo below to see how tight it was).

The company I bought the belt from (SignalsUK) was super helpful and based in the UK too. The belt arrived a couple of days after ordering. Although it was thicker than the original it did appear to work OK so I will include a direct link to it here. They supply hundreds of different belts and electronic spares so they’re a handy company to have bookmarked.

The belt is very easy to fit. Use your tweezers to place it around the motor spindle and around the other pulleys following the path in the photo below. There is a small plastic tab that protrudes out of the case towards the black plastic wheel. The gap it leaves is very small (you will find it at around the 8 o’clock position) so be careful not to snag or damage the belt here. There will be a a degree of tension in the belt and this is normal so you will need to stretch it a little over the final wheel.

AIWA HS-PC202

The 1mm thick belt – notice how it is practically rubbing against itself where it passes back beneath the left-hand brass pulley wheel.

Replacing the Belt (Take 2)

If a jobs worth doing, it’s worth doing properly – so I continued my search for a better fitting belt. Eventually I stumbled upon a place that custom manufactures belts for a variety of machines, including the AIWA HS-PC202 Mk3. The Mk3 is apparently mechanically identical inside to the Mk2 and so the belt they supply for the Mk2 also fits the Mk3. Here’s a link straight to the correct belt – here. The company, FixYourAudio, is based in Slovakia and is run by a very helpful guy who makes the spare parts purely as a hobby to help enthusiasts keep these old machines alive. A week or so after ordering my belt arrived in the UK so I have no qualms in recommending them. It is ever-so-slightly thinner than the original but is definitely a better fit than the 1mm thick one.

Putting it back together

Before you finish off – if you have any additional problems with your player such as unwanted ‘scratchy’ noises when turning the volume wheel or when the headphone jack is twisted in the socket then take advantage of the opportunity and squirt some DeoxIT on them whilst you’ve got the player open. Don’t forget to operate the volume wheel fully a dozen or so times to work the fluid into the pot and clean it up. Likewise for the headphone socket, squirt some in and then insert the plug and twist it around in circles a bunch of times to clean off the contacts.

Now you just need to put it all back together. If you knocked off the slider switches then pop them back on now. You will notice that one side of them is hollow and this will sit on top of the appropriate switch sticking out from the circuit board. The larger of the two fits on the Dolby NR slider whilst the other belongs on the Tape Bias switch. Don’t forget to place the little round spacer back over the DC input port. There is a little flat spot on one side of the circle and this should be positioned facing the outside of the case so that it fits flush against the flat edge of the backplate.

You may need to press and squeeze gently in a few places, particularly around the play button to get the tab to engage in the lug correctly. However you should not have to force anything. If you feel any resistance stop and check, reposition the backplate, check the spacer and/or the position of the slide switches and try again. Once it has popped back into place and you are happy with the fit all around, replace the 3 screws and you should be good to go! Enjoy the new lease of life your personal stereo has been given!

How to access IMAP email on an Amiga 500 in 2018

 

Update – May 2019 – I’ve now tested this setup with the latest version of SimpleMail (0.45) and am delighted to report that everything still works and you can still access IMAP email on an Amiga. The instructions remain exactly the same too. For reference I’m also using Roadshow 1.13 and AmiSSL v4.3. What’s even better news is that the updated version of SimpleMail is both faster and more stable than its’ predecessor!

Yep, you read the title correctly, this article is a step-by-step guide on how to access IMAP email on an Amiga 500 in 2018! This works with any IMAP email system including Gmail!

Who would have thought 30 years ago that we’d be able to get electronic mail on our Amiga 500 computers in 2018. It really is a testament to both the original designers of the Amiga and to the ingenuity and tenacity of the current community that this is actually a real possibility now. In this guide I’ll show how to get it working, step by step. It’s entirely feasible and actually works really well! Read on to find out what you need and how to get it configured.

What you need

First things first, you need to head on over to the SimpleMail website to download the latest version of the software (currently 0.44). Click on the downloads page and select the appropriate installer file from the list. I’m using Workbench 3.9 so downloaded the simplemail-0.44-0s3.lha file. If you’re using anything less than Workbench 3 then I’m afraid you are out of luck.

The download page – choose the OS3 version.

One you’ve download the installer go ahead and install it and meet me back here for the next step. If the program doesn’t run then go back and check the readme file. There are a number of additional custom MUI classes that it requires to run and you may need to download and install one or more of these too.

Launching SimpleMail

Find the folder where you installed SimpleMail and open it. Inside there should be a Readme, an AmigaGuide document and the program itself. Double-click the SimpleMail icon to launch the software. After a brief splash screen you should be presented with the main application screen. This is the point at which we can begin to configure the program to get our emails.

How to Configure your email account

Select “Configuration…” from the Settings menu and then Accounts from the configuration screen that pops up. This is where we can add our account and do lots of other things later on to get the mail program working just how we want it.

access IMAP email on an Amiga

Here is how you access the configuration screen.

The ‘Accounts’ section of the configuration screen.

Adding your email account

The next step is to add your email account and you start the process by clicking on the ‘Add’ button in the top right of the window. I should point out that the program has very helpful tool-tip descriptions that pop up if you hover the mouse pointer over a particular button or text entry box for a few seconds.

access IMAP email on an Amiga

Click this button to begin adding your email account

The account name can be anything you want – this is just a label so you know what the account represents in the future. Enter your name, email address and reply address (if you want one) associated with your email account.

access IMAP email on an Amiga

Entering the account name and personal info relating to the account

Setting up IMAP – the ‘Receive’ configuration

  1. Click the IMAP4 radio button in the ‘Receive’ section..
  2. Enter your IMAP server name in the ‘Server’ box.
  3. Enter the port number in the ‘Port’ box.
  4. Ignore the Fingerprint box for now – this will be automatically filled later on.
  5. Select the type of security your account uses next to the ‘Security’ drop-down menu (for SSL select TLS).
  6. Enter the username and password you need to authenticate with in the ‘Login’ and ‘Password’ boxes respectively.
  7. Lave the rest of the settings in this section as they are.
access IMAP email on an Amiga

Entering your IMAP details

Setting up SMTP – the ‘Send’ configuration

  1. Enter your SMTP server name in the ‘SMTP Server’ box in the ‘Send’ section.
  2. Enter the port number in the ‘Port’ box.
  3. Ignore the Fingerprint box for now – this will be automatically filled later on.
  4. Select the type of security your account uses next to the ‘Security’ drop-down menu (for SSL select TLS).
  5. If your SMTP server requires authentication (most do these days) then click the ‘Use SMTP AUTH’ tickbox.
  6. (If required) Enter the username and password you need to authenticate with in the ‘Login’ and ‘Password’ boxes respectively.
  7. Leave the ‘Login into POP3 server first’ and “Use IP as domain” boxes unticked.

Entering your SMTP settings

Testing your setup

Now it’s time to see if everything works! Click the test button over on the far right. This will first test your IMAP settings and then run through your SMTP setup to make sure everything is in order.

access IMAP email on an Amiga

Testing your account settings

You will see the following error appear twice, firstly for the IMAP connection and secondly for SMTP. Click ‘Trust Always’ to have SimpleMail  save the certificate ‘fingerprint’ so this error doesn’t re-appear in the future.

access IMAP email on an Amiga

This error will appear but it’s OK to click Trust always as you know this is you email provider.

Now in order for these 2 fingerprints to be saved permanently, preventing any future warnings from popping up every time you try to download or send email you must save the configuration using the ‘Save’ button at the bottom left of the configuration window.

access IMAP email on an Amiga

Prompt reminding you to save the configuration.

Correcting Errors…

Now at this stage you might end up with the following screen with everything highlighted in red! Don’t panic – this just means that the test failed due to an error in one or more of your entries. Go through and double/triple check every piece of information you have entered. Make sure the ports are correct, there are no typos in the server name etc.

The problem in my case was the passwords as mine contain numerous weird and wonderful characters. Now this isn’t normally an issue but for some reason the keyboard mapping on my Amiga was wrong so these characters were actually appearing as something else entirely when typed…

You cannot see the password you are typing so I highly recommend opening up a shell window and typing your password into that just to check it appears correctly. Once you have ironed out any kinks with getting it to appear properly, go back to SimpelMail and enter it again in both boxes.

access IMAP email on an Amiga

This screen means you’ve made a mistake somewhere!

Final steps

Hopefully you’ve got every bit of information correct now and can see a screen similar to the one below with the fingerprint boxes fully populated.

access IMAP email on an Amiga

Success – IMAP and SMTP settings have been correctly entered and tested,

Don’t forget to click on ‘Save’ at the bottom left of the configuration window otherwise all your hard work up to this point will be lost!

access IMAP email on an Amiga

Don’t forget to SAVE the configuration!

After you have saved the configuration you will return the main program window. You should see your newly added email account appear at the bottom of the folder list. At this point it will not have downloaded any of your emails or even folders for that matter.

access IMAP email on an Amiga

Your new email account initially appears like this…

Accessing your emails

Now click on the name of your email account and SimpleMail will connect to your email server and download a list of all the folders within it. This will include your Inbox, Sent items etc. along with any custom folders your have created too. This might take a few seconds – you can see what is going on by checking the status bar at the bottom of the window.

access IMAP email on an Amiga

You will always know what is going on by checking the status area of SimpleMail

 

access IMAP email on an Amiga

Your email folder heirarchy

At this stage the program still hasn’t downloaded any of your emails. To do this you must left click on any of the folder titles for it to fetch the contents of it from the server. In the below example I clicked on my Inbox and it fetched 17 mails from the server. This took just a few seconds – if you have hundreds or even thousands of mails it will take a bit longer.

access IMAP email on an Amiga

This is the progress bar. If you have a lot of emails then it will move quite slowly

 

access IMAP email on an Amiga

Finally – Viewing an email!

Even though the messages are now displayed in the list view, these are only email headers. The body of the messages have not been downloaded. Click on an email to download the message – the body will be display in the bottom right viewing pane. If you would like the program to automatically download full messages you can of course enable this but it will greatly slow down the process of fetching emails.

Unfortunately SimpleMail does not yet support HTML mails so you will only see the plain text version of them like the example below. Personally this doesn’t bother me too much as most HTML mails are sent from companies trying to sell you stuff. Friends and family send plain text emails so I can live with that.

Example of how HTML mails are presented

Downloading Complete emails rather than just the headers

As I mentioned above, you can have SimpleMail automatically download complete messages, including the full body. It does make reading through your mailbox quicker, but at the expense of longer fetch times. Only you can decide if the trade-off is worth it. To do this, left click on the folder or Inbox you want to make the change to and select settings.

access IMAP email on an Amiga

Selecting the settings option

Now you should see a window like the one below. Select ‘Complete mails’ from the ‘Download’ drop-down menu and then click OK. The next time you perform a fetch/click on that folder it will download each and every message inside it in full.

Getting the software to download Complete mails instead of just the headers

Renaming your email account

You may have noticed that your email account has an odd name. The program seems to name the account itself based off the server it connects to. Don’t worry though, you can easily change it to something more recognisable. Simply right-click on the mailbox name to bring up a folder menu and select ‘settings’.

access IMAP email on an Amiga

Selecting Settings option in the Folder menu

Here you can enter the name you want to appear in the folder list by entering it into the ‘Name’ box under Folder properties. Hit ‘OK’ at the bottom of the window when you are done.

access IMAP email on an Amiga

Entering your mailbox folder name

You should now be back at the main program window and your mailbox should be named correctly in the folder view.

Concluding

And that is it – you can now access IMAP email on an Amiga in 2018!

SimpleMail is constantly being worked on, so if you are reading this in the future there may well be a better version out with even more features.

I have only given you the bare minimum instructions here to get you started with accessing your email. There are plenty of other things this software can offer. Mail sorting rules, signatures, integrated address book and so on. You can also resize each of the viewing panes or remove them completely. Have a play around with it all and enjoy.

Gmail!

I run my own mail server but this should work for any IMAP email out there. I have personally tested it with Gmail and it works perfectly. Here’s a screenshot of the configuration screen so you can see what settings I used.

Gmail configuration

Some extra info about system requirements

For the record I got this running on an Amiga 500 with a Vampire V500 V2+ accelerator card. The biggest advantage this offers is speed – up to 12 times faster than a stock A500! You certainly don’t need a Vampire to run SimpleMail though. What you will need is Workbench running off a hard drive or CF card solution, a TCP/IP stack and SSL software. I’m pretty sure you would also need at least an 68020 CPU or suitable accelerator card to get any of this running at all.

Of course this isn’t just limited to Amiga 500 computers, that just happens to be what I use. It should work just as well on the big box Amiga’s and of course the A1200 too.

Anyway, I really hope you found this article on how to access IMAP email on an Amiga both interesting and useful – if you did please let me know! If you have any questions or requests then drop me a message and I’ll do my best to answer them.

Adding an SD Card Slot and HDMI port to an Amiga 500

SD Card Slot and HDMI port to an Amiga 500

So you may be aware that the Vampire V500 V2+ Card gives your vintage Amiga 500 both a MicroSD card slot and an HDMI port for hooking up to a modern display.  Trouble is the ports are on the board itself which is rather inconvenient if you don’t want to leave the top of your Amiga’s case off.  After doing a little research and searching around I discovered that you can get some nifty little extension cables for both ports which will allow you to ‘move’ them to the exterior of the Amiga’s case.  This post will explain how to add both an SD Card Slot and HDMI port to an Amiga 500 computer.

SD Card Slot and HDMI port to an Amiga 500

Location of the HDMI and MicroSD ports on the Vampire card. Not exactly easily accessible once the lid is back on!

Purchasing the right cables for the job

The HDMI cable was a little tricky to locate at first as there are just so many options. Once I got the search term correct I stumbled into the right cable for the job.  The cable I bought (below) was an Adafruit Panel mount HDMI Cable - 40 cm which you can pick up from Amazon.  It’s just the perfect length and almost seems tailor made for the Amiga!

SD Card Slot and HDMI port to an Amiga 500

40cm HDMI extension cable

The MicroSD slot extender was a much easier product to locate.  This Micro SD to SD Card Extension Cable I picked up from Amazon is perfect.  You will find that you can actually get both MicroSD to MicroSD and also MicroSD to SD extender cables.  I decided to chose the MicroSD to SD option as I thought it would allow a little extra flexibility in terms of what cards I can use with it.  With it I have a choice of using both regular SD cards or  MicroSD cards now with the use of a MicroSD adapter card.

MicroSD Extension Cable

Deciding where to locate the ports

I decided the HDMI port needed to be at the back of my A500 but that the SD card would be much more useful if it was located somewhere along the side.  There is quite a lot of free space underneath the floppy drive, ample to accommodate the HDMI socket.  However because the SD Card Slot is housed in quite a chunky plastic case there wasn’t room for it under the floppy, plus I already have my floppy boot selector switch there anyway.  So, I chose a spot that sits just under the keyboard where there is plenty of space and it’s also super convenient for me to pop cards in and out.

Final Cable Routes

Creating the cut-outs and securing the new ports

The slots for both ports were cut out using a Dremel tool (if you have one you should know instinctively how to do this!). Take care to use a low speed otherwise you risk melting the plastic.  The ports themselves are held in place with some hot glue, perfect for this sort of project as it flows freely around things before setting hard.  I used a few blobs of hot glue to keep the SD extension ribbon cable out of harms way too as it’s quite fragile.  It could easily become trapped and get damaged by the A500 keyboard when it is replaced if it was left unchecked.

End Result

I’m pretty pleased with the end result, with hindsight I probably should have tidied up the HDMI cut-out a little with a file as there are a few rough bits left… but it’s around the back of the case and out of sight so no biggie.  The HDMI port is rock solid and should have no problem with me plugging and unplugging a cable in and out.  Likewise the SD card slot is nice and secure and more than up to the task of dealing with regular card swaps.  Perhaps a version in white (or off-white LOL) would have been better but I just couldn’t find one for sale anywhere.

Improvements?

Only other thing I might do in future is add an RJ45 extender when the Apollo Vampire team make the Ethernet port expansion option a reality.  Although I already have Ethernet through the use of the fantastic little plipbox device this is currently hogging my parallel port so I cannot print without first unplugging it – hardly ideal.

Formatting the SD Card

Installing the Vampire V500 V2+ in my Amiga 500

Vampire V500 V2+

With the arrival of the weekend it was the perfect time to give my A500 the Vampire V500 V2 treatment!

Getting started – removing chips

First off I needed to remove the original Motorola 68000 CPU and the Kickstart chip.

Installing the card

The next step involved carefully inserting the Vampire board connector pins into the empty CPU socket. This actually took a hell of a lot more force than I thought it would. I’ll admit I was scared of damaging the CPU socket or the motherboard itself with the amount of pressure I had to exert. Anyway it eventually slotted in all the way and no harm was done. Please do make sure you remove both the CPU AND the Kickstart chip though – this wasn’t mentioned in my instructions (but they’ve been updated since I got mine to mention this). If you don’t remove the Kickstart chip then the Vampire board won’t sit flat and the CPU connections may be unreliable. Thanks to Igor Majstorovic for taking the time out to let me know about this!

Vampire V500 V2+

Cables & CF Card setup

The next step was to hook up an HDMI cable to the socket on the board and fit a Compact Flash ‘hard drive’ to the Vampire’s 44 pin IDE header. I opted for a 32Gb CF card as this is the size of the Apollo OS (Coffin) image. (This is a pre-configured Workbench 3.9 system that you can download and use with your Vampirised A500.

Imaging the card was simply a matter of downloading the Apollo OS image from here and using Win32 Disk Imager in Windows 10 to write that image to my Compact Flash card.

For once in my life everything went as it should and when I powered up my Amiga 500 it worked! As Hannibal would say; ‘I love it when a plan comes together!’ I was greeted with a really cool Vampire logo boot screen after which the Workbench loaded just a few seconds later.

Fitting an External, Boot – selectable Gotek Drive to an A500

Amiga Gotek External Cable

I wanted to avoid having to have one of these hanging off the back of my A500.

I wouldn’t really call this an upgrade as such, more taking advantage of the latest developments in the Amiga scene. In case you’ve never heard of it, the ‘Gotek’ drive is basically a 3.5″ Floppy Drive emulator. Instead of putting floppy disks in it you plug in a USB flash drive that can contain up to a thousands Amiga Disk Files or ‘ADF’s’ (floppy disk images).

There are quite a few versions of these floating around on eBay, internal and external. I decided pretty early on that I wanted mine external so I could keep my A500’s DF0 as a real floppy drive so I opted for an external drive. I wanted to have the install look as authentic and neat as possible so I opted to install my Gotek inside an old external floppy disk drive that I picked up off eBay for spares/repairs. If you want to do the same just be careful to pick one that houses a regular sized floppy drive and not a reduced height, slim one as the Gotek won’t fit. You can see what I mean from the photo below which shows my finished Gotek drive underneath a couple of Roctec slim drives – it should be pretty obvious that the slim drives don’t have the necessary height to accommodate the Gotek drive.

The other choices available now include the option to have an OLED screen that can display the name of the ADF file you select and the track info and also a built in speaker that can simulate the noises of the real thing. It’s more of a buzzer than anything else but it’s pretty effective and much better than sitting in silence waiting for Cannon Fodder to load!

Amiga 500 Super Denise Upgrade

The A500 machines shipped with a graphics chip called ‘Denise’ that is responsible for handling sprites and also all the different screen modes and resolutions you can use with Workbench and other apps. The later Amiga 500+ model sported an updated chip called ‘Super Denise’ which offered quite a few more screen modes and resolution options. The Amiga 500 Super Denise upgrade is a very straightforward modification which simply involves getting hold of the newer chip and replacing the old one with it. (It is an exact pin-for-pin replacement). For more detailed info on the Denise chip look here.

Getting hold of a new chip

The ‘Super Denise’ has the chip number 8373-R4 whereas the old regular ‘Denise’ is 8362. You can usually pick up Super Denise chips on eBay – here.  I paid around £20 for mine which I though was fair… be patient and wait for one at a fair price – don’t get ripped off.

Removal & Replacement of the chips

You can remove the the old chip with just a small flat bladed screwdriver if you are careful. Just lever up each end slowly, alternating from one end to the other, making sure it lifts evenly from each corner so that the pins don’t bend. Ideally though, use an ‘IC Extractor’ – it makes the job a lot easier and is a useful tool to have in your retro computer toolkit anyway. Again these are readily and cheaply available on eBay – here. The new chip should just plug straight into the socket. Make sure the marked end of the chip matches up with the notched end of the IC socket. If it goes in the wrong way around it won’t work and may even damage the chip and/or the motherboard. If the pins don’t quite line up you can bend them gently into place using a pair of pliers.

Amiga 500 Super Denise Upgrade – In Pictures

Below you can see before and after screens showing SysInfo details, and available screenmodes along with the two different Denise chips fitted. The end result is a success with more screenmodes (eg Super-Hi Res modes) available straight away, even with my standard 1084S monitor. However in order to benefit from the rest of the modes the Super Denise chip offers (such as Productivity) I need to get hold of a proper Multi-Sync monitor that can handle the different refresh rates they need.

Repairing a Roctec Floppy Drive for an Amiga

Repairing a Roctec floppy drive

This is a guide to repairing a Roctec floppy drive for an Amiga 500 computer.  I thought I’d write this up as much for my own benefit as other peoples so I can refer back to it in another 20 years! LOL.

Roctec Amiga external floppy drive

If you ever pop a disk in your external Roctec drive and hear a strange whirring noise and can’t read any of your disks then the chances are you are suffering from a perished or broken drive belt.

Perished Drive Belt

Perished Drive Belt

These drives use a rubber belt to connect the drive motor to the spindle hub. The rubber belt only has a finite life and given most of these drives are getting on for 30 years old now it’s hardly surprising that they expire.

cof

No tension in old perished belt

The good news is that it’s pretty easy to replace them and I’ll give an overview of what you need to do here.

Getting Started on the Repair

The first thing you need to do is undo the 6 screws on the underside of the drive case using a small philips screwdriver.

Underside of drive case

Remove these 6 phillips screws.

This particular drive case is made from a solid metal rectangular tube so you need to slide the floppy drive out. The aim here is to slide everything out of the BACK of the case. The first step is to gently slide the floppy drive forward out of the case far enough to detach the plastic fascia from the front of it. Unless you do this it won’t slide right into the case and out the back. There are 2 small tabs on each side of the fascia which you can gently bend with a small flat-bladed screwdriver and it will pop right off. Don’t force anything or it will break – it should come off easily.

Drive Fascia removed

Drive Fascia removed

Now you need to prise the back part of the drive out of the case using something thin enough to slide into the tiny gap between the case and the backplate, I found the blade of my pocket knife to be perfect for this but be careful not to injure yourself or damage the plastic/paint on your drive! Once you’ve got it moving slide it out slowly (a slight side to side wiggle can help here). It will be attached to the floppy drive via a ribbon cable so keep going until you’ve got the floppy drive out too.

The floppy drive has a thin metal cover that protects the mechanical innards and it is held in place by some little tabs on the edges and a solitary screw at the back right (when viewed from the front).

Roctec Floppy Drive Rubber Belt Path

Replacing the Belt

Once the top is off you can see the drive mechanism, motors, heads and so on. Carefully remove what’s left of the old belt with a pair of tweezers. Be careful not to touch the drive heads with anything metallic or you may damage them. The photo above shows the path the rubber belt follows, indicated by the yellow line.

The next step is to remove the drive motor which is attached to a metal bracket that runs across the back of the drive. It is held in position by one screw in the far left corner and another on the right a few cm down from the corner. Don’t touch the two screws with the large flat heads either side of the motor. Be careful you don’t pull the bracket too much as there are two tiny wires connecting the motor to the circuit board here so be careful to support the bracket whilst you are handling the drive to replace the belt.

How to detach the motor and bracket

Once the bracket and motor are out of the way you can carefully thread a replacement belt around the large drive wheel, small tension wheel and keep a loop ready at the top right to go on the motor spindle. Follow the yellow path in the earlier photo and take you time as it can be a little tricky to get the belt into place. A small flat bladed screwdriver and a pair of tweezers are essential for this. Don’t forget the belt needs to thread behind the small silver pully wheel as this is what tensions the belt.

Close-up of the small tension wheel you need to thread the belt behind

Once you’ve got it threaded around the wheels correctly you need to get the final loop onto the motor spindle. It helps if you grab the loop with some needle nosed pliers here and pull it taught with one hand whilst guiding the motor spindle into the loop with the other. Once this has been achieved (it may take a few goes as it’s quite fiddly) place the bracket back in place and rotate the large drive wheel slowly and check the belt stays on, is running where it should and isn’t fouling any components.

Look carefully through the tiny gaps in the top of the drive motor you should be able to see the motor armature slowly rotating as you move the belt. If it is then job  done, time to put it all back together! If it isn’t then don’t fret, just double check the belt is following the correct path, isn’t twisted anywhere and hasn’t slipped off any of the wheels.

Congratulations, your Roctec drive should now be fit for active duty for another several years now!
