Together with a FrankenApple there were a lot of different ROM chip included.
Most notable are 1 set of 4 '78 Integer Roms (1-4) as well as a single '77 Week 51 F8 Integer ROM.
Most of the custom ROMs seem to be for use in a Mountain computer ROM+ card.
Several programed 874x type MPUs were included as well.
UPDATE: some Roms are now in the ZIP archive.
There were some modified monitor ROMs as well as several tools for ROM testing.
