I have been trying to run diagnostic tapes on my PDP-11/40. It seems
that I am missing the documentation for many of the CPU diagnostics.
Does anyone have a listing for the 11/40 instruction exerciser? My paper
tape is MAINDEC-11-DCQKC-A-PB.
I load the tape and start it at 200 and it runs for a while and then
begins printing out:
PASS #0000 PC=015354 PSW=000000
PASS #0000 PC=015356 PSW=000000
PASS #0000 PC=015360 PSW=000000
PASS #0000 PC=015352 PSW=000001
PASS #0000 PC=015354 PSW=000001
PASS #0000 PC=015356 PSW=000001
PASS #0000 PC=015360 PSW=000001
PASS #0000 PC=015352 PSW=000001
...
This seems to run indefinitely.
I have tried several different switch setting as described in the PDP-11
Diagnostic Handbook recently online at bitsavers, but it always ended up
with this result.
Anyone have information on this diagnostic?
