SparcStation 1+ - have keyboard, will error

In a previous installment of the SparcStation 1+ saga, I got the machine to present a serial console to one of my other old computers, but couldn’t get any video out of the video card or boot to an actual operating system.

Super Famicom Repair-O-Rama!

I bought a large lot of Super Famicoms off of Japanese auction for cheap, and set about trying to repair them. Almost all of them had problems.

The C64 is alive!

A power supply arrived from Ray Carlsen, and it works great. I spent the time while I was waiting by soldering a really bad video cable. I only managed to melt one DIN plug in the process!

Building a keyboard adapter for the early PC8801. (Part 1 - Research)

If all goes well, I will soon be the owner of an NEC PC-8801mkII “Model 30.” The platform is famous in Japan, as later models of the PC88 featured a ton of independent games, including many from developers who would go on to create games that were popular worldwide (Thexder, Snatcher and Ys all got their start on this platform). It also has a lot of trash, but neither of these things are interesting to me right now. I’d be happier just getting the computer to work (not least, because as a non-SR mkII, there are very few games I can enjoy on it anyway).

Reassembling the Amiga 2500, Part 1 - Hard Card

Things are starting to get hectic again with real life, but there was still some time recently to work on the Amiga 2500. My objective was simple: get the machine back together into a working box again so it is no longer spread all over my workbench.

Commodore A501 memory expansion battery removal

When I first got my Amiga 500, it wouldn’t boot. Suspecting something was wrong with the A501 512K memory expansion, I pulled the card, at which point it did boot. It didn’t take me long to realize that battery corrosion had killed it.

SparcStation 1+ - setup

My streak of actually trying computers that are in my pile continues with this SparcStation 1+. While it has been a very loyal and very handsome monitor/keyboard stand for the last few years, it would probably be more interesting as a functioning computer.

Commodore 64 pickup

I picked up a Commodore 64 off the local classifieds. It came with a 1541 floppy drive, a bag full of blank floppies and tapes, the C64 itself, the infamous black finned power supplies that kill C64s, a Rixon modem, and a Nortel multi-line keyset from the 90s.

Amiga 2500 keyboard refurb

The keyboard I got with my Amiga 2500 had:

  • A broken right alt key,
  • A spotty (at best) return key,
  • And a numpad enter key that wouldn’t stay up, but did work,
