MFM drives.
Vertex V150
Miniscribe 6085
ST 4038M Seagate Franklin telecom AT-40
Miniscribe 3650 HH
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.
I'd suspect that at least a few of these were from PERQ systems, given
their provenance. Vertex V150s and Miniscribes were commonly used in the
T2 models. As another listmember mentioned, Dave Gesswein's MFM emulator
will image these (and can decode PERQ hard drive formats.)
(If you do manage to capture PERQ images, please let me know...)
