SiliconRE

Traces, schematics, and general infos about custom chips from the 80's and 90's, mostly video-game related, reverse-engineered from silicon die pictures.

Thanks to Jotego for the many bug reports and contributions.

Chip database with references, date, manufacturers, silicon IDs, descriptions and donators (if in my collection): https://docs.google.com/spreadsheets/d/1-4YH3xBQobYJ0NR4TNJO10mzUCcyNdEzlFjsFldoQjc/edit?usp=sharing

Please reach out if you're working on any of these so I can update @'s and links. This kind of work can be very time consuming, it would be a shame if several people worked on the same chip without knowing (even though that could help cross-checking for errors).

Cell lists

Check out Cells for cell lists and detailed traces for a few vendors. If you're reverse-engineering a gate array, this will save you a LOT of time.

Die photos

Check out Dies for low-res photos of dies in my collection that I haven't scanned yet.
