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 didContinue reading “Fun with “Stuff””

Quick Update on Multiple Projects
I’ll try and keep this informal this time 🙂 The Atari 2600 seems to have a bad 6507 CPU. The voltage drops to zero when it’s inserted. I have a replacement on its way Of the CreatiVisons, I managed to get one to boot fine and one just gives black screens. The tape drive works.Continue reading “Quick Update on Multiple Projects”
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 upContinue reading “The Big Haul”
Update on all the PCBs
So remember all those PCBs I ordered? Let’s break down what worked and what didn’t. What Worked So first up, both my ROM adapters worked without a problem. So we now have a Low Profile Amiga ROM switcher and a Low Profile Microbee ROM switcher. Both built around using turned pins to keep the profileContinue reading “Update on all the PCBs”
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”
Not a Soldering Iron in Sight
Updates Starting with an update on existing projects, I have the Amiga MIDI project working. I’d accidently crossed the input and output lines on the MAX2323 chip. A quick bodle later and it was working. It’s now corrected in the master PCB. I also have permission from Grzegorz Kraszewski to release my version. That wasContinue reading “Not a Soldering Iron in Sight”
Another Productive Break
So, having a week off, I decided to move on a few projects. While not completely successful, I did make some good breakthroughs. Leading up to the break, I started a repair on a huge old CRT TV, It’s not working… yet but I think I just need to check some things on the insideContinue reading “Another Productive Break”
Not much going on…
Mostly I have been working on building a Retro Chip Tester so I can start diagnosing things faster with the Amigas. This is actually for the Artifactory, but I plan to use it for a bit before I drop it off to them. If nothing else, I want to get through the backlog of 4116Continue reading “Not much going on…”
Mutant Bee. Tac 2 Repair
While I work on a special project, I’ve been paused on all but the most basic work. One project I did do (And had fun doing) was upgrading my Microbee Personal Communicator up to being a PC85b. This was literally just a swap of the top “core” board for the one I had left overContinue reading “Mutant Bee. Tac 2 Repair”
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?”
