These were in common use on Z89's and Z-90's. Heathkit used drives made
by
Tandon and Siemens. The Siemens drives were kinda unique: It used a
disk with a spiral groove for the head positioner.
The cabinets are among the best floppy enclosures ever made IMHO
(although
they can be a bitch to put back together). I have several of them
myself.
The (linear) power supplies in 'em are fairly beefy.
