The TM10 Magnetic Tape Control was the magnetic tape controller for the early PDP-10 models (KA10 and KI10) which had the PDP-10 I/O Bus as a standard bus.

There were two versions, the TM10A and TM10B; the latter used the DF10 Data Channel for data transfers, to reduce the load on the CPU.

It connected (per DEC-10-HTMB-D) to TU20, TU30 and TU40/TU41 magnetic tape drives, and the TU10 in 'Slave' configuration.

The 'TM10 Magnetic Tape Control Maintenance Manual]' (DEC-10-I4AA-D) refers (on pg. 1-1) to it working with a 'TU79', but this must refer to the earlier drive of that name.
