The full story

Casey Bralla's Rockwell AIM 65, a late-70s microcomputer with a QWERTY keyboard, a 20-character display and a thermal printer, is miserable to program line by line. Hackaday covers his solution: generate a WAV file that mimics the machine's cassette interface and play it in, so whole programs load from audio instead of being typed.

An independent community project. Not affiliated with Anthropic.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
