a place to store my junk
I picked up a Sega Mega Drive 2, which was minging dirty and had a sort of plastic rattle inside, but still seems to work fine. I decided to give it a quick clean and to investigate the rattle. This is my MK-1631-50 Mega Drive #430373179 So popping the case off and it’s even more […]
Invader From Space is one of the older Grandstand games, this one is from 1980. Although I never owned one of these back in the day I remember playing it a lot. I picked this one up from Ebay for £20, not a huge bargain but they do go for a lot more sometimes. I […]
I received this AMRAM-16 512k memory / ram expansion for Amiga 500 series inside an Amiga I purchased of ebay. The Amiga has really bad battery corrosion damage on the board and I am going to refurbish that as part of a separate project. This card was not working when I tested it in another […]
My clone of Simon was (almost) ready in time for Christmas, I am delighted with the finished article. Conclusion It was a hugely rewarding experience, forcing me to dust off a few skills I had not used since I was a child and the opportunity to learn something new. While it took longer than I expected […]
One of the final steps in the process was to enclose this in a case. ABS Plastic Enclosure Originally I intended to use a black ABS plastic case off the shelf. I found these cases online or a few pounds and thought they would be perfect. However when I drilled them, the cuts looked untidy […]

Because I intended to get the PCB manufactured I needed to get some PCB design software. I used a piece of software called Fritzing which can be downloaded from fritzing.org for free. Once installed, learning to […]
I recently bought a Commodore 64 from ebay. In the bundle I got this Digicom Packet System. I know it was used by Ham Radio enthusiasts but have no clue how it works. I know the guy who used to own this Commodore 64 made this box from a kit. I think it is technically a […]
Ok the next stage is to get some actual code running. I found a code sample here. http://www.randomterrain.com/atari-2600-memories-tutorial-andrew-davie-08.html created a local file asmtest.asm Because I created a new terminal session I need to run these two commands again. export bB=~/Atari2600/bB export PATH=$PATH:$bB I used this command to compile. Joes-MBP:samples arkleyjoe$ dasm.Darwin.x86 asmtest.asm -I”$bB/includes” -f3 -lasmtest.list.txt […]
My wife wanted to do some printing using a daisy wheel printer. I purchased a KX-WD55 Daisywheel Printer from ebay. I got ready to connect it up, only to realise that it was specifically designed to work with the KX-WL55 Word Processor Laptop and has a special proprietary connector I did not recognise. It is definitely […]
My bathroom mirror has a light inside of it. The bulb went and so I opened up the mirror to replace the it. Once opened I realised there were a huge amount of empty space and I thought about adding a bluetooth speaker set up inside. It took me about 2 days to complete the […]
