I Like 8 Bits and I cannot lie

Being a blog about my adventures in Retro Computing

    My goodness, it’s been a while!

    Hi Intarwubs. It’s been a while since my last post. Things have been very slowly proceeding, and then, like unplugging a cork, there has been a huge rush this long weekend. Updates on the last post So some quick updates on everything covered in the last post. Firstly the Microbee ROM switcher is working fine. […]

  • Some new additions, some new repairs

    Some new additions, some new repairs

    While the last few weeks have been busy, they haven’t been that busy on a retro front. I realised I’d ordered the wrong Floppy Disk controllers for the Microbee and the MSX controller, so I had to order replacements. They’ll take quite some time to get here, but that’s OK. Due to some financial commitments […]

  • Stuff coming down the pipe

    So it’s been a while since I did anything major. I did do another spin (My third so far) at the laser cut Microbee case, which revealed I needed to refactor parts of it. I tried to make a fastening system so the upper half and the lower half could be screwed together, but I […]

  • Upgrading the VRAM in a Quadra 950

    Upgrading the VRAM in a Quadra 950

    So you have a lovely Macintosh Quadra 950 with only the onboard 1MB of VRAM, and you want to upgrade it to the full 2MB? Here’s how. Firstly you will need 4 sticks of compatible VRAM. These come in either 256K or 512K sizes. While you can use 512K sticks, only 256K will be visible […]

  • Some upgrades for the Quadra 950

    Some upgrades for the Quadra 950

    Thanks to the ever generous Greg, I have received several NuBus cards to my Macintosh Quadra 950. They’re provided in a “unknown” state, so it’s going to be a fun job to install some of these and see what we can get working… So what do we have here? First up we have a generous […]

  • The Archimedes is back on the bench

    The Archimedes is back on the bench

    Now I have an oscilloscope, I thought it was time to break out the Archimedes. So far it has resisted my attempts to diagnose exactly what is wrong with it but I will persevere. Symptoms are the same whether I use a Gotek or a real drive.When you try and access the drive you get […]

  • Posting will slow for a while

    Posting will slow for a while

    So I’ve gone back to work after an extended holiday, so output is likely to slow for a bit. However, I’m still doing retro “stuff” so I thought I’d share some of it. One of the coolest projects I completed on the weekend was building an MT32Pi Hat. This consists of a Raspberry Pi running […]

  • Expanding on removing corrosion caused by batteries.

    Recently in a Facebook chat, the question was asked: “How do I deal with battery acid damage so things don’t get worse?”. Having recently dealt with both the Quadra 950 and the Amiga 2000, I felt eminently qualified. Here is my answer This is my method. There are many like it but this is mine. […]

  • Understanding Memory Chip Codes

    I wrote this up for a forum post and thought I’d share it here. It’s not 100% accurate but is “good enough” to help in a lot of cases. The discussion started with a poster trying to understand how we knew what the capacity of a 41256 RAM chip was. It’s actually there in the […]

  • Bits and Bobs

    Bits and Bobs

    Well, here we are again. Amiga 2000 I built up the -5v rail for the A2000 and fully reassembled it. Unfortunately the A2000 is presenting with a black screen. No synch or other signs of life. Not the end of the world, but it does mean it’s on hold until my new Oscilloscope arrives. Mac […]

I am always interested in your old systems! Consoles and Computers.
