The Systems Concepts DC-10 is a PDP-10 disk controller interfacing with IBM 2311/2314 compatible drive. Actual drives used at MIT was Memorex model 660 , compatible with the 2314, and later double density Calcomp, model 215, also compatible with the 2314, but offering double density.
The PDP-10 I/O device covers two device codes: 610 and 614 which are conventionally named DC0 and DC1.
