I replaced most of the caps in the in the PSU but it was still making an odd high-pitched noise before resetting. Ruh-roh, maybe there's a problem with one of ICs died. A little looking around I spotted a thin line in one of the vertical boards. Thar's your problem: I'm thinking the odds of...

I had a batch of these printed up in nylon resin to fix some broken keys on a Ti99/4a keyboard and they seem to fit really well. Endorsed. I have a dozen or so extras I can stick in an envelope if anyone needs them.

I picked up a selection of ISA & PCI expansion cards from somebody this evening and they had a box full of IEEE Computer magazines from the early 2010s. Print magazines aren't my bag but I can act as an intermediary if someone wants them. My example photo was worse than I expected but you can...

I left the house to pick up a Powerbook G4 off Craigslist and stumbled onto a treasure trove of old stuff from a friend's garage. The headliner is a Lisa with a Profile drive: We couldn't find the top case for the Profile drive nor the cable and controller card, yet. The Lisa mouse was also...

I scored this historical oddity today. 1983 dual-processor (8088 and a Z80), 256k of RAM, dual 400k 5.25" floppy slots sharing a single drive motor, a 10MB HDD, and 12" monochrome CRT. Oh baby. While taking it apart to clean and inspect I discovered that it was a completely tool-less and modular...
