Good news: I'm going to get a reader on loan so I should be able to
image these things. I'll put them up on my web server here, if anyone
would like to take a look at them let me know.
On a positive note it looks like the Perq T2 units used either the ST506
or ST412 drives, so those *might* have Perq data as I don't think Bob
ever had a Pro/350. Then again could be rainbows, is there a PERQ
emulator out on the web or does anyone know what a Perq disk would look
like?

As the excavation of Bob's junkpile continues I have finally hit the MFM
layer. Specifically about 10 5.25 hard disks that look to be old style
MFM drives.
Vertex V150
Miniscribe 6085 (could be 3b1)
ST 4038M Seagate Franklin telecom AT-40
Miniscribe 3650 HH (40mb maybe for a 3b2)
Seagate ST4096
Priam ID45-H
Rodime RO203E
RD54
Real ST506
Pair of ST412's.
Anyone recognize what kinds of systems may have used these? The RD54 is
of course DEC, and I'm guessing the ST506 and 412's were from either a
Rainbow or a Professional/350. But the rest are weird. Maybe Convergent
miniframes? Probably not PC's as Bob had a lot of weird stuff.
Thoughts? I'll see if I can get a mfm reader and suck data into files I
can post for others to read/try/giggle at. But as there isn't much
labelling I have no idea what is on them.
Also did find Wordperfect and speller for what I think is Rainbow on
5.25 floppies. Let me know if you need a copy, or if a copy exists in
archives (also two DEC disks for Learning the Rainbow or something like
that)
