1X0023 PROBLEM: Power supply fault (S-280 Only).
RECOMMENDATION: Does Not Apply.
1X0024 PROBLEM: Argus (Acorn) in Dual processor configuration- contention problem.
RECOMMENDATION: Does Not Apply.
1X0070 PROBLEM: PPI has given an invalid interrupt status response or interrupt w/ no status.
RECOMMENDATION: Locate and replace defective PPI.
1X0071 PROBLEM: Interrupt device code “77” detected. This device code does not exist.
System clears each interrupt source from DC=1 until the INTA code ≠ 77.
RECOMMENDATION: Possible CPU Backplane jumpering problem. Locate and correct.
1X0077 PROBLEM: During a call to a user mapped space interrupt routine, the software
jumped thru RDOS location 0 (Trap) indicating a CPU or Memory failure.
RECOMMENDATION: Locate and Repair Memory bus failure.
If a system error condition causes a PANIC to occur, bit zero of the panic code word will be reset to zero and the
remainder of the word will contain the system error code. Refer to Appendix A for system error codes.
4-2 - Fortran/RDOS Codes
System errors may also be posted as Fortran (Appendix C) or RDOS codes. They are as follows:
