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.Continue reading “My goodness, it’s been a while!”

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 commitmentsContinue reading “Some new additions, some new repairs”

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 runningContinue reading “Posting will slow for a while”

Not the end of the world, but it does mean it’s on hold until my new Oscilloscope arrives. MacContinue reading “Bits and Bobs”

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, ICContinue reading “Upgrades, Problems, Parts”

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 stemmedContinue reading “Repairing Microbee No3 Keyboard”
