Re: Clock Error

I am sure this is nothing useful, but FWIW, when I did take a copy of
the disk image running under SIMH and booted that on a real 4000/60, to
determine if a SIMH disk image was really a raw disk image and thus would
boot from a SCSI emulation card, I got an odd time error message beyond the
expected "invalid TOY clock time" error:
