Well done...
I thought so :-)

HP 9825 tapes at the HP
FWIW, the 9877 contains a small PSU (based, IIRC, on the 9825 PSU), 1-4
tape drives, the same number of controller cards (electrically and
mechanically idendentical to the one in the 9825) and a little interface
PCB. The last is the only part that's really 'custom' for the 9877.
I assume it connects to the 9825 using a 98032 16 bit interface.
Correct. somewhere I do have the installation manual for the 9877 and it does clearly
show a 98032 interface. I don't remember the option number of the interface but
it's probably 77 or 077. That seems to be typical of how HP assigns option numbers on
the 98032.
Do you
(or anoyne else) have the wiring for the cable and the
jumpers for the
98032?
No, that's another thing that needs to be found. NASA does have the interface on
theirs but I couldn't get them to give me any info about the jumpers or anything other
than the interface PN.
That's something else I've not managed to find (98032s I have,
plenty of them).
Same here.

program for it till now. The tape APPEARS to be
in good condition but
you know how HP tapes are :-(
If it is readable, can the 9877 be used to duplicate it?
It should be able to. AFIK the 9877 will duplicate all 9825 tapes. Accroding to an
x-HP engineer that was one of the 9825 developers, the 9877 was designed specificly for HP
factory use to mass duplicate 9825 tapes so I would think it would duplicate everything.
I don't remember if the 9825 has a file protect command or not but if so then it might
not duplicate protected files.
Let's just hope that this tape is good. I need to find somebody that has a 9825
with REAL good tape drive and that can read this tape and make some copies. I'm
wondering if there might be any way to read and duplicate the tape that would be gentler
on it. Any ideas?
