I'm sure this is a familiar question to many - does
anyone have a list of the two-digit codes displayed on
the PDP11-73 during power-up ? I am resurrecting a
dormant unit which stops at '1' (I have only the CPU
and memory installed in the backplane) I'm not sure if
this is a good or a bad code. Any help would be
appreciated.
Thanks,
David Comley
Dave, the Error Code 1 = cpu error
1. Make sure that your cpu diag switches are correctly set
2. Make sure your +5vdc and +12vdc power supply is good
3. Make sure your eproms do not have any bent pins
