What disk is that? DF32 or some kind of RK?
Neither. Others here have been discussing that it's a Recomp disk (a
system I know nothing about). A DEC DF32 would have many fewer heads
and a very thick (6mm? 8mm?) platter. AFAIK, all RK disks have a
linear positioner.
I didn't know anything about the Recomp-II before either. There is a
brochure in the bitsavers directory:
http://www.bitsavers.org/pdf/autonetics/recomp/
that presents an overview of the machine, and the pics directory has
some great photos showing the internals.
Desk size, solid-state, disk-based-memory, targetted at engineering-
type problems. In a class kind of like the vacuum-tube, drum-memory
Bendix G15, I'd say.
I wonder how much design influence the Recomp-II may have had on the
Minuteman GC (D-17B), looks like there could have been some
continuance there.
