The full story

CompuServe Web is a working recreation of the 1980s CompuServe online service, written in Pascal and reachable from a web browser or a Telnet terminal. Logging on as a guest shows the service as it was, and page codes such as GO CB or TOP come from an OCR'd copy of the CompuServe user manual.

Claude helped the builder sort out multi-session threading. New accounts wait up to 24 hours for a sysop to approve them.

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.
