The controller that goes with is a transistor based

Yes, it is a drum, for sure. Seems to have a LOT of heads.
The controller may be a regular disk controller, or can be
used with both. I noticed an "on cylinder" light on the
panel. But, it should be pretty easy to repurpose a disk
controller to handle a head-per-track drum.
