The '''TC11''' is the [[DECtape]] controller for the [[UNIBUS]]. It supported, and was normally provided with, [[TU56]] dual DECt6ape drives. (In theory, it could probably have controlled the earlier [[TU55]] single drive, but this is not confirmed.) There is only one version of the TC11.

Like many of the earlier large peripheral controllers for the [[PDP-11]], the TC11 was a large custom [[wire-wrap]]ped [[backplane]] which bolted into the front of a 19 inch rack, such as an [[H960]]; into it plugged about 40 small M-Series [[FLIP CHIP]]s.

==Board chart/count table==

The Flip Chip module utilization chart for the TC11 backplane is as follows (* = Connector):
