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.
Pictures on? ftp://ftp.dreesen.ch/Unknown_CDC_Stuff
Anyone can identify this ?

if you look on bitsavers under cdc/catalogs

lists several drum storage units including the models 861, 863 and 865
the controller looks a little too early to be for the BG504A
the one you're trying to identify looks to be using 1604/160 series modules

My mistake, sorry, that papertape reader was of course obvious. Removed that pic.
Added 4 more, that are from some frontpanel that probably is also CDC.
Quite easily the most complex I have ever seen, but somehow strange.
Maybe for a tester rather than a computer.

Ed, I don't know if you (or anyone else) can see this, but there's two
junk characters at the end of every word you write. I see it in Alpine
and it makes your text nearly unreadable. :)

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.

If you get back over there, try to find CDC ID tags on the drum and controller.
There would normally be a model number badge somewhere on the outside.
Being that there was a 350 paper tape reader, I'm guessing its for one of their
smaller systems,
maybe an early model 1700

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.
