DEC used 3 phase in RP04's. RP04-II (DEC internal pre-release RP05's),
RP05's, and RP06's used two phase motors, as did (IIRC all the RM02/3/5's).

RP07's may have been three phase -- but I don't know. The
RP04-II's/RP05/6 were Memorex. The RP04's and RP07's were ISS Sperry
drives. The RM02/3/5's were CDC 9762/9766's.

Anyone ever see an RM04?

Did they ever build a slower RM05 for Unibus boxes?
