Josh,
The HP-IB interface shouldn't be a big problem, but you'll need a HP 98034B
or a revised A version.
The standard HP 98034A version doesn't support high-speed CS80 drives.
If you want to part from one of the machines I would love to give one a new
home.
If you want to replace the ROM's I've several romboard pcb's (Angars design)
so you can replace the system rom's by flash memory ( I'm not 100% sure they
work for the 9845A I'll check it)
You should ask Tony nice, if he reverse engineered the diagrams of the HP
9845A yet.. (he did the 9845B already)

Onderwerp: HP 9845A service/user manuals?
Hi all --
Anyone have a service manual for the HP 9485A (not the B or C)? I picked
up
three of these machines in fairly good physical
condition just a couple of
days
ago, but their operating condition leaves something to
be desired :).
I've looked in the usual places (hpmuseum.net, and hp9845.net) but I can
only
find the manual for the B/C revisions. My
understanding is that the "A"
version is
different in some ways (not really sure what the
hardware differences are
yet.)
The good news is that one of the three 9845s just required some careful
reseating of the cards and ROMs and it now appears to be working correctly
(I
haven't yet tested the printer (no paper yet) and
I'm assuming the tape
drives
will require a bunch of work, assuming I ever find any
tapes to use). I'd
love to
get the other two running as well, hence the need for
the service manual.
All
three appear to be complete (with I/O, Mass Storage,
and Graphics option
ROMs), now if I could just get my hands on an HPIB interface...
Thanks,
Josh
