Has anyone have or know where to get an IBM XT (5160)
diagnostic ROM? I am
trying to revive an original IBM XT motherboard which is nonresponsive and
gives no error codes (beep or POST).
I am not even sure such a ROM exists but it would be a 27C256 style EPROM
that plugs into an IBM XT motherboard to help fault isolate an almost
completely dead unit.
It DID exist. Todd Fischer? made a diagnostic ROM. It came with a serial
board, and required that you supply a terminal. The chances of my finding
mine are zilch. Unlike a POST card, it could diagnose a dead CPU, etc.
If anyone can help, I would much appreciate it. Thank
you in advance.
I don't think that it is much help to tell you of the existence of
something unobtainable.
