The Systems Concepts DC-10 is a PDP-10 disk controller interfacing with IBM 2311/2314 compatible drives. Actual drives used at MIT was Memorex (model 660?) and later double density Calcomp (model 215?).

The PDP-10 I/O device covers two device codes: 610 and 614 which are conventionally named DC0 and DC1.
