Dave,
Oh, I am so sorry. What a disappointment that had to be. I would think somewhere
there has to be a good copy of that BP2 V2.7 Well, hopefully the PDP-11 C V1.2
is good since it is different.
I had a really interesting trip the the living computer museum in Seattle yesterday.
At this point they have in running state a PDP-7, a very nicely equipped PDP-8,
a couple PDP-10s (KI-10 & DECsystem-20),
a PDP-11/70 (DECsystem cabinet running UNIX), a PDP-12, plus a Xerox Sigma 7.
It is amazing to see the blinking lights on this old hardware.
They were next working to get a CDC 6600 running. That looked like a big job.
It's great that Paul Allen has decided to make all this possible.
Best Regards,
Mark

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.
:-(
The C v1.2 image, though, is different. I'll spend some time on that
tonight.
