When the unit is powered up, there is no output to the
terminal, and the
processor fault LED's give a code of 14, which is listed as "Scope Loop" -
does anyone know what this signifies?
The original meaning of 'scope loop' in DEC diagnostics was a tight loop
that kept on accessing some failing piece of hardware so you could use a
non-storage 'scope to debug it.
I would assume, based on the fact it's code 14, that it's fairly early on
in the power-on diagnostics of your 11/23+ system, and that there's
smething fairly fuandamentally wrong with the CPU/memory/bus.
