Macintosh SE/30 Logicboard recreation

This is a recreation of the Macintosh SE/30 logicboard.
It is not a 1:1 copy of the original logicboard but instead the original schematics were used to completely redesign and route a lookalike board.

Reverse engineered PALs

The original PALs have been reverse-engineered and equations were rewritten to match the behaviour of the originals - the provided JEDEC files are not dumps of the content of the original chips.

The provided JEDEC files are intended to be used with a 16V8-type device (GAL16V8, PALCE16V8, ATF16V8) as a replacement for the video, clock and RAM-signalling PALs. Certain low power ATF16V8B don't work. ATF16V8C use pinkeepers instead of internal pullups and might be problematic as well.
