Visited an older collector recently, and in his shed

The controller that goes with is? a transistor based? monster on
countless small pluginboards.
Pictures on? ftp://ftp.dreesen.ch/Unknown_CDC_Stuff
Finally got enough patience to let the images load.
Pulling a guess out of the thin air or some other place, my guess would
be a CDC Digigraphics controller, which used drums for display refresh.
