The TD8-E Simple DECtape Control is a DECtape device controller for the OMNIBUS, such as in the PDP-8/E. It is intended for use with the TU56M (dual transport) and Tu56HM (single transport) variants of the TU56 DECtape Transport. It is a programmed I/O interface, implemented as a single quad PCB, the M868.
