I've put the partially reverse-engineered 9895A firmware on Github:
https://github.com/brouhaha/hp9895fw

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.)

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.

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.
