Assembling the Microbee MultiROM

So I have finally got a design for a “MultiROM” ROM changer suitable for use with the PC 85, capable of fitting in a standard case in the ROM H position at IC 22. https://github.com/cheshirenoir/BeeMultiRom Assembling these is a little non standard so here’s a guide. You will need: The PCB. 32 turned pins. YouContinue reading “Assembling the Microbee MultiROM”

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 aContinue reading “What Next?”

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. NowContinue reading “Going for some doubleyous, boys.”

My goodness, it’s been a while!

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”

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. MacContinue reading “Bits and Bobs”
