List of chips that have been converted (or are in the process of being) converted back to layout and/or schematic. Where possible the data is linked below

Partial chips that have had only the mask ROM, sub-circuits, etc are not counted. Basic logic chips are not counter either.

Also a big list here: https://project5474.org/

  • SVN handles partial checkouts making large files easier to work with
  • Sourceforge isn't great, but it was the only reasonable SVN hosting I could find
  • Sourceforge hatemail will be ignored without a reasonable alternative suggested
