TM11 magtape controller

The TM11. TMA111 and TMB11 magtape controller are a series of UNIBUS device controllers, used with the TU10 and TS03 1/2" magtape drives. They are compatible both in their interface to the drives, and in their programming interface.

The TM11 and TMA11 are almost identical in construction; they are implemented as a series of smaller standard FLIP CHIPs in a custom-wired 19" backplane. The TNB11 is a re-implementation, using two larger custom boards (one hex and one quad), along with 4 UNIBUS-specific FLIP CHIPs (M105, M795, M796, M7821), which plug into a custom hex-high four-slot system unit (for a BA11 box).
