According to the field maintenance manual scans, if you hold the
board chip side up with the connectors at the bottom, it's about
1/3 of the way up the board in the gap between the leftmost two

like it could be a 28 or 32 pin chip.

ROM, which is supposedly on the board which -doesn't- have the ROMs
that contain the microcode, on the way right edge of the board, on

Yeah, I kinda wish I had access to some of his code, in case he got
any further than I have so far.
