First most of the ROMs for the 85 are available from my site
http://www.series80.org/Images
You will need, however, the 82929A Programmable ROM drawer
(check http://www.series80.org/Manuals/HP82929A.pdf to see how
it looks like), to be able to use the ROM image on your 85.
BTW if you have the 82929A, then you can also download the EMS
ROM which allows a far greater selection of drives to be used
with your 85.
Come to think of it, the EMS ROM code is quite small, so I wonder
if some person who understands 85 assembly can turn this into a
binary utility so that it can work elsewhere in memory.
Anyway, you may also get the Mass Storage ROM (manual at
http://www.series80.org/Manuals/HP85-MassStorage.pdf)
on eBay. This will allow the 85 to talk to 9121 3.5 inch drives which if I
am not mistaken will work with your 1631D analyzer.
Some day I may finally produce the HP 85 ROM emulator, but the way things
are going, don't hold your breath :-(
BTW I have finally managed to get a 98155A keyboard for my 9915's
(the embedded version of the the 85, brochure at
http://www.series80.org/Manuals/HP9915A.pdf)
I am also expecting a bunch of manuals for the 9915s. I hope to have them
up on my site by the end of the month.

But they did! Its called the HP Integral
PC. Its faster, more compact,
has an ergonomic keyboard, and even has Unix when you want to go around
the back and fiddle with things.
Too bad its not as cute as the 85.

Argh, and I bet I
won't have too much luck finding an 82929A module anywhere
:(

I'm hoping it would work with the 9122, which is what I want to get for my
1631D. The only reason I'm hunting for 9122 instead of 9121, is I thought
the floppy disks for the 9122 might be easier to find (they DO use different
media right?)

I saw note of that on your website. That
would be soooooooo so nice to have
an ROM emulator. Humm there can't be THAT much to the electronics inside the
82929A. Anyone have one they'll let me take apart and build a copy of?

Nope, they both use the standard 720K disks. I'm not sure but the 9122C
(emphasize C) might reguire 1.44Mb disk but it's a very different animal
than the 9122 D and S. 1.44 disks WILL NOT work in the 9121 and 9122D/S.

Good! I'll have to book mark that one.

Congradulations! Where did you find it? It took me years to find one.

GREAT! I've been looking for those for years. The only one that I have
is for networking the 9915s.

It's not going to be that simple -- the HP85 CPU bus is somewhat strange...

As you've doubtless realised by now, it's just a matrix of switches, and
the matrix layout is the same as for the HP85 (the service manual for
which is easy enough to obtain, on the MoHPC CD-ROMs). I think I posted
the DB25 connector pinout a few months back -- if not, I can dig it out.

Eh? I think the Integral is a much nicer machine (both in electronic
design and styling) than the 85...
