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.
Dos the 9845 support CS/80 drives at all? I thought that to use HPIB mass
storage you needed a 3rd party ROM (e.g. the one from SSI) which is not
easy to find.
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)
Alsa I haven't, mainly because I don't have a 9845A. It's not high on my
list of things to look for, alas. If one is offered, I'll accept it with
geatful thanks and reverse-engineer it, but there are other things I
would rather own...
