If anyone has dumped the ROMs from the HP 9895 (8-inch) or 82901/82902
(5 1/4-inch) HP-IB disk drives, which use the Amigo command set, I'd
appreciate copies of the images, ideally along with the HP part
numbers of the EPROMs (probably 09895-xxxxx and 82901-xxxxx).
For that matter, I'd be interested in ROM images from any of HP's
other HP-IB disk drives, floppy, hard disk, or combined.
Also ROM images from the 9114A and 9114B HP-IL disk drives. I already
have one ROM image each from the 9114A and 9114B, but there were
multiple firmware versions.
Thanks!

Hi Eric,
I have a 9121 HP-IB disk drive I can try to extract the ROM from
(using an old EEPROM programmer I have).
Regards,
Vlad.

The ROMs in my 9114s are 09114-15514 REV R.
Need an image? What type/size are they?

There 27128 (16KB).
There are at least five known ROM images for the 9114A/B, and I have
images of two of them. I'm not sure whether 09114-15514 Rev R matches
one that I already have. If you don't mind dumping it, that will be
appreciated. After I've collected a few of these, I'll put them up on
a web page and post the URL to the list, in case anyone else needs
them.
John R. Baker established a precedent for using the contents of the
first two bytes to identify the 9114 firmware revision; I don't know
with certainty that that actually uniquely identifies all revisions.
John wrote an HP-71B program to read the first two bytes over HP-IL.
It should be possible to read the entire contents over HP-IL, but I've
found it easy to pull the EPROM and read it with an EPROM programmer.
John identified five firmware versions:
09114-15514A first two bytes 80 a7 - from 9114A
09114-15514B first two bytes ad fc - probably from 9114A
09114-15515 first two bytes d8 b1 - not sure which model
09114-15516 first two bytes da dc - not sure which model
09114-15521 first two bytes 10 8d - from 9114B
I have images whose first two bytes match the -15514A and -15521,
courtesy of another list member, though I don't know the exact HP P/Ns
that were on the labels. The -15514 image I have has the first two
bytes 80 a7, matching the -15514A in John's list, and has a checksum
(sum of all the bytes, modulo 64K) of 81ce. The -15521 image I have
matches the one in John's list, and has a checksum of 112a.
Some years ago I did a fair bit of study of a disassembly of a 9114A
ROM image, but unfortunately seem to have misplaced the results. I'm
not sure whether I'll do it again. IIRC it had a few more DDT and DDL
commands than were defined in the Filbert (82161A tape drive) command
set, and it also had an entirely different command set which I later
found out was SS/80, for use by the HP 110 Portable and Portable Plus.

For drives of that general ilk.... I have:
9121
9122
9144
7957
Let me know if these would be of use.

Looks like my ROMs are the first ones in your
list, 80 A7 in the first two bytes (drives are
9114As).
I'll send you the image anyway, just in case.

If anyone has dumped the ROMs from the HP 9895
(8-inch) or 82901/82902
(5 1/4-inch) HP-IB disk drives, which use the Amigo command set, I'd
appreciate copies of the images, ideally along with the HP part
numbers of the EPROMs (probably 09895-xxxxx and 82901-xxxxx).
I have (I hope) an 82901 somewhere. Somewhere could mean in one of the spare
rooms here, it could mean in my storage unit (which is harder for me to get it from).
I hope it wasn't something that was 'lost' in the move.
According to the schematic I traced out, it contains a pair of 2K ROMs, I think
pinout as 2716. Numbers 1818-1834 and 1818-1835. The 1818-1834 is the top
of the memory space, 1818-1835 just below it (6802 processor so it reads the
reset vector from the top of its address space).
Do you want me to try to find it and dump the ROMs?

Yes, please. If you can find it fairly easily, that will be great.
