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.)

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.

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.

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.

I'm working on implementing these devices on my MAME-based simulator of
HP9845B systems.


Where is the firmware on the 9895A? Is it in a 24-pin DIP package mask
ROM near the lower right corner of this picture?

Hmm, looking in the service manual it appears there were several
versions of the controller board. Some with multiple PROMs and some
with a single ROM, and some with a Z80 and some with an MC2
(micro-CPU, the '2' is a superscript).

I have a 9895A. Don't know which version of the controller PCB it has
without digging it out to take a look.
Yes that would be it the unpopulated positions would be for versions of 
the controller using smaller ROMs, The one I have is the 4 ROM version 
and I am pretty sure I dumped them, I just need to find out where.

Hi everyone,

does anyone of you happen to have the images of the firmware ROM of
HP98034 module and/or of the HP9895 disk drive, please?
I'm working on implementing these devices on my MAME-based simulator of
HP9845B systems.

Thank you.
