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”

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?”

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”

A Tale of Two Systems (And their Horrible Batteries) Part 1

In parallel, I’ve started fixing both the Amiga 2000 and the Quadra 950 boards. Both had extensive battery damage. In both cases I’d neutralised the battery alkaline with vinegar, water and isopropanol washes. I started with the Amiga. AMIGA 2000 Evaluating the board, I ended up pulling off all components and sockets in about aContinue reading “A Tale of Two Systems (And their Horrible Batteries) Part 1”

Updates and some Smaller Projects

Well I haven’t stopped working on projects and while some of the have been successful, others have not been so successful. It doesn’t help that my desoldering station has broken. I just need to get some specialised glue to fix it. Archimedes The Archie still has a bunged Floppy Disk Drive and I’m stumped asContinue reading “Updates and some Smaller Projects”
