[Simh] TOPS-20 4.1 BUGHLT

[Timothe Litt]

The first part is self-explanatory.  QUASAR looks for SPOOL: (usually
ps:<spool>)
early in initialization.  It's not there.  It's possible that the
logical name is not/mis
defined.  Either RCDIR% or GTDIR% returned "Structure is not mounted".  If
you believe the successful "crash saved in ps:<spool>quasar-nsd-crash.exe"
message, it's the logical name.  Perhaps the TSU that you applied updated
QUASAR from the hard-coded ps:<spool> to the logical, but didn't define
it.  Or perhaps the message is optimistic and/or ps:<spool> is corrupt.

The bughlt could be anything.

Together, probably a corrupt disk - perhaps an unclean shutdown caused a
page
write to be incomplete.  You can try running CHECKD.  You can debug &
fix with
some mixture of eddt, mddt & filddt.  Or you can build a new PS:.  If
necessary,
there's an excellent chance that your local software specialist can
recover data
from the old one.  If you can find her.

As with any corrupt disk, the more you try to run it before it's fixed,
the worse
the chances of complete recovery as data will be reused.

Disk space is now so cheap that the easiest way to backup these systems is
to simply copy the SIMH disk images (with the simulator stopped after a
clean
OS shutdown.)  That's my recommendation for all SimH machines... These disks
are smaller than your typical video (or a couple of hundred photos).

This communication may not represent my employer's views,
if any, on the matters discussed.
