    Converting a PAL TRS Colour Computer to NTSC

    When I got my CoCoSDC, I was surprised how many of the games out there relied on NTSC Artefact colour to generate either some or all colours. It was close to 80%, and even higher in the more commercial games. After a while I decided I wanted an NTSC system. As I had 3 CoCos, […]

    Total Joystick Madness

    I have been busy 🙂 Now I have all the different computers working, it was time to get interfaces for them so they can fulfil their prime purpose. To wit: Video Games! Texas Instruments TI 99/4A I have a PCB design ready to go for this, but in the meantime, I decided to make a […]

    Hippo Gnu Ear

    Well, it’s a new year and I’m still waiting on things I ordered in November 😀 Firstly, you’ll most likely have noticed I moved to a new host. There are a few “goodies” I can get with the new host, including plugins, so I have moved. Last year featured a LOT of PCB design and […]

    A Whole Lotta Nothing

    I’m not dead. Honest! It has, however, been a long time between posts. Unfortunately I haven’t been working on project work as much as I would have liked, and I spent a long time waiting for parts to arrive for projects.

    The Long Haul

    So recently I managed to participate in an exciting retro-computing “thing” in the form of clearing and organising a seatainer full of old computers and peripherals. While most were not systems I was interested in (So many dead printers, for instance), there were some gems that I took home, as did my fellow participant. This […]

    Fun with “Stuff”

    I do apologise that I haven’t been updating as much as I could. There’s been personal things going on in the background that have slowed my output down. Atari 2600 The replacement 6507 CPUs arrived and after hitting a dud, my second chip worked fine. This is why you always buy a couple. I did […]

  • The Big Haul

    The Big Haul

    So on the weekend, as part of a local organisation, I did some volunteer work. In return I got some old systems donated to me. And what a donation it was! While none of this equipment is in what I would call a “working state”, it’s all fixable and it’s all super interesting. First up […]
