The DF10 Data Channel is a channel for the early PDP-10 models (KA10 and KI10) which had the PDP-10 main memory bus as a standard bus. It can connect to multi-port memory banks either directly, or via an MX10 Memory Data Multiplexor. It is also connected to the system's I/O bus, to allow the CPU to control it.

It has limited capabilities, compared to most channels from other manufacturers: it supports only the following types of channel command words:

  • End of program
  • Jump to new CCW list
  • Discard data
  • Transfer data to/from memory

It is used with device controllers such as the RP10 disk controller‎ and the TM10 Magnetic Tape Control.
