  • What Next?

    I’m in a contemplative mood today, and I’ve been thinking about my collection. Specifically I have been thinking about what I want to get next. Here are my thoughts. Computers At this point I am really not going out of my way to buy any more computers with two exceptions. If someone offers me a…

  • Going for some doubleyous, boys.

    (Obligatory Letterkenney reference now complete) So it’s a long weekend, and thanks for some confluence of leave, for me it was a four day weekend. Such a nice thing occasionally. Friday I spent mostly working on general chores, but in the evening I thought I’d finally drag out a project to start looking at. Now…

  • Life Gets in the Way

    Life Gets in the Way

    It’s been nearly a month without a post. While some things have happened in the meantime, not a lot of new developments have occurred. Microbee: First the bad news I was supposed to be bringing one of my Microbees to the Perth Amiga Users Group gathering, so of course, I chose the DRAM 128k with…

  • My goodness, it’s been a while!

    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…

  • 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…

  • 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…

  • Upgrades, Problems, Parts

    It’s been an exciting few weeks. Archimedes The Archimedes continues to confound me. I finally got a replacement 1772, plugged it in and… No change! At this point I have swapped out all the chips that feed the floppy disk. If you look at the schematics, I have socketed and tested IC29, IC30, IC38, IC…

  • Repairing Microbee No3 Keyboard

    The third Microbee was now nominally “working” insomuch as it was booting reliably to the command prompt. Only thing is, I couldn’t test anything further without a keyboard. The keyboard was partially working, and having removed the keycaps I could see a mix of 3 different keyswitches. White stemmed with a horizontal bar, Black stemmed…
