Visited an older collector recently, and in his shed he has a strange thing, labeled CDC, that somehow looks like a drum memory, but then again not ( drum looks too small to be usefull )

The controller that goes with is a transistor based monster on countless small pluginboards.

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.
