I?ve sent F.Ulivi the contents of the single ROM version from my 9895A, along with some
preliminary reverse engineering work on the contents that I?ve done in conjunction with
Eric Smith.

If you have not gotten the HP 98034 ROM image yet, I can try to dump mine when I'm
back from travel next week. I suspect you want the "revised" version, which is
the interface that works with the HP 9895. I have both versions.
Craig, I'd be interested in your 9895 ROM dump and reverse engineering info too.

Thanks, I'd appreciate it if you could dump the "revised" 98034 firmware.
By the way, I'm working on R.E. of the 9895 hardware. I should have
something useful in a few days. Is anyone interested in it? It would be
a sort of "dump" of my notes on the hardware, nothing very polished.

Ah, by the way, I've already asked for 98034 firmware to the owner of
hp9845.net site. He should be working on the dump.

Very interested, I have one in the restore queue

I've put the partially reverse-engineered 9895A firmware on Github:

So far we've figured out some of the Amigo command parsing and some of the
PHI chip accesses. (PHI was an HP custom SOS chip for HP-IB.)
