I recently rescues an HP3000/922LX system running MPE/iX.
I am able to boot but don't have the password for OPERATOR.SYS. Is there
any way to get around this on the console?
A related question: I have installation tapes of MPE/iX versions 4.0, 5.0
and 6.0 and would like to make an archive copy of it. Problem is, these
tapes (NMRESTORE and other formats) mix different block sizes on the
same tape. Is there an easy way to copy the tape to disk, keeping track
of the block sizes, so I can rebuild the tapes later if needed?
I know the trick
dd if=/dev/nrsa0 of=/dev/null ibs=65536 obs=1 count=1
which will let me know the blocksize of this particular block. I could
repeat this for the whole disk but there's got to be an easier way :)
