Wanna bet!
Anyone have one they'll let me take apart and build a copy of?
I may.

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.
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.
Argh, and I bet I
won't have too much luck finding an 82929A module anywhere
:(
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.
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?) Some day I may finally produce the HP 85 ROM
emulator, but the way things
are going, don't hold your breath :-(
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.
