The tape read cleanly, but again I do not know where this came
from...it has a handwritten label indicating that it's BP2 v2.7, but it
may have actually been written from the corrupted tape image in the
trailing-edge archive. That archive has been around for long enough for
this to be a concern.
Is there anyone hanging out tonight who would like to assist me in
testing this?
Ok, nevermind. Bad news. The image I got from that tape is
byte-for-byte identical to the corrupted tape image from the
trailing-edge archive.
:-(
That is really sad. Oh well, it was worth a try.
As for the question on how to verity it. If you just hook it up to an
RSX system, mount it foreign, and do a "FLX <tape>:[*,*]/DO/DI", and
you'll either see something sane, or something crazy...
The C v1.2 image, though, is different. I'll
spend some time on that
tonight.
No need. The PDP-11 C tape is a BRU tape image. My tool can repair it if
it is broken. In addition, I already have a good copy of that tape.
