The CP (CPU) errors mean that the console processor (8085) couldn't get a proper response out of the main CPU. Possibly a missing board, mis-seated board, or no memory at location 0. Also, a failure to start can be caused by missing bus grant continuity or a missing 9302 terminator module. I sug- gest you send direct mail to me and we can set up a time for a phone call when you're at your 11/44.
