Notes
PALs from both 128k and 512k prototype boards are untouched dumps from unlocked chips. They are identical between both boards with the exception of the BMU0 which differs between both of them.
It looks like the dumps are identical to what would be found on a production 128k/512k board. While slight differences have been discovered between the prototype dumps and the PALs found on a production Macintosh Plus board, the 128k/512k dumps are interchangeable with the corresponding parts on a Mac Plus board.
The files in the Macintosh Plus section below have been rewritten and compiled to be used for 16V8/20V8 and in case of the prototype TSM dump converted to a 16V8 Jedec file.
