The DC-10 from Systems Concepts is a PDP-10 disk controller which interfaced with IBM 2311/2314 compatible drives. It connected to both the PDP-10 I/O Bus and to the PDP-10 Memory Bus; it did not need a separate channel (e.g. a DF10).
The actual drives used at MIT were Memorex Model 660, compatible with the 2314, and later Calcomp Model 215's, 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.
The DC-10 shared hardware with the Systems Concepts DK-10, using the same memory bus interface.
