I have a 4951. It uses the same tapes as the HP-85, HP 9825, etc. IIRC they're
DC-100 tapes and you can use the same (40MB?) tapes that were used in PCs. You can also
reformat and use DECTapes. But check your drive first, you'll probably find that it
has the same problems (melted tape drive roller) as the HPs usually do.
I acquired a pair of HP-4952A protocol
analyzers. One has version
1.00 1986 software, the other A.02.00 1989 software...
Also, I'm looking for a copy of the terminal emulator that came with
these. I know the diskettes can't be copied on the unit, but I'm sure
they could be copied on a *nix box.
Can't help you with floppy-based HP analyzers, but it leads me to ask
about my own - I have a pair of portable HP protocol analyzers (I
*thought* the numbers were 4951A and 4951B, buit they do not use 3.5"
floppies (that's the 4951C, AFAIK); instead, they use the same sort of
tapes as a DEC TU-58).
I did find this PDF on a Google search:
http://www.helmut-singer.de/pdf/hp4951c-4952a-4954a-4955a-4972a.pdf
Doesn't solve any problems, but it's a nice feature reference.
We did lots and lots with ours, including simulating an IBM 37X5 (PU T4)
up to and including the BIND, with enough RR traffic to fool our PU T2
product into thinking it was logging onto a real system. It's harder
than it sounds, especially given that the menu-based "programming
language" does not allow much creative latitude. I suspect that newer
analyzers (like yours), especially those mentioned in that PDF file,
would have better SNA support. In any case, they were stunning for
BISYNC traffic. Not sure we ever used them for async monitoring, but
they _will_ do it.
Are there any other HP analyzer owners on the list? I'd love to swap
any information.
My 4951 is in storage but I'm pretty sure that there's a operators manual
with it.
