Uh, oops... You are exactly right. The 11/34 manual is indeed talking about
the M9301 and not the M9312. I have a M9312. Problem #1 solved.
Mand that lysdexia!!!
The only thing now is to figure out why the switches are set as they are. My
unit's switches point somewhere in the console emulator ROM, but not at one
of the two valid entry points specified in the M9312 manual. Either:
A) That's the original ROM and wherever the switches point happens to
work as an entry point. The previous owner may have set them this way,
possibly to bypass some of the diagnostic tests.
B) That's not the original ROM and the switch settings are correct for
whatever ROM is now in there. The previous owner may have replaced the
ROM.
C) The switch settings are wrong.
Could it hurt to simply plug the board back in and try it out, assuming the
rest of the machine is OK?
