Johnny,
I don't recall if the layered product patches were there or not. I am on the road
and I was able to verify the F77 compiler version:
F77 /ID
F77 -- PDP-11 FORTRAN-77 V5.4-26
Does the -26 indicate a patch level?
Thanks for the info on non-routed DECnet and HECnet. I may have had some other issue
going on and need to work on getting connected again.
BP2 with I/D space would be worth some effort to bring back from extinction. With the
high speed of Simh and E11 with modern CPUs, if one could figure out a way to reassemble
the tape blocks in the various combinations the see if BRU could read it successfully or
not in some automated way, then just let the CPU have at it. It can't be worse than
breaking the Enigma code in World War II.
Also, I meant to say that the PDP-11 C V1.2 is corrupt but the V1.1 is okay as I
recall. Also, DECUS C works quite well, but I don't recall which DECUS tape it is on.

Dave,
If you are using the RSX11M+ V4.6 distribution tape, there is a copy of F77 (V5.4 I
think) on it already. Look in [246,246]. Also, that tape has DECnet on it as well that
works fine with Johnny's TCP/IP software.
Cool. Did the person setting that up also include the layered product patches that are
included with RSX?
Unfortunately, the DECnet on that tape is for
non routing nodes, so that complicates direct connection to HECnet. I have not found a
RSX11M+ V4.6 routing DECNet distribution.
It don't really complicate any connection to HECnet. You do not need a routing node
for that, and unless you have some very specific needs, routing nodes just means it
requires way more CPU and memory usage.
You are right on BP2 V2.7 being corrupted. The
V2.5 is good though. On the PDP-11 the latest one is corrupt but the earliest one is ok.
V2.7 have some improvements that would be really nice to have, such as split I/D space
capability...
I have been trying to repair the tape on trailing edge, but there is a big library file
in there which is just way complicated to figure out...
