The TM11, TMA111 and TMB11 magtape controllers are a series of UNIBUS device controllers, used with the TU10 and TS03 1/2" magtape drives. They are all 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).
For both the TU10 and TS03, the controller connects to a 'Master drive', which includes extra electronics; additional 'Slave' drives may be connected to the Master drive.
Drive Connection
The connection to the master drive is a standard dual-width BC11-A cable, as used for the UNIBUS. This is the pinout for the TM11 (the other two are basically identical to this):
| Pin | Signal | Pin | Signal |
|---|---|---|---|
| AA1 | SEL0 | AA2 | |
| AB1 | SEL1 | AB2 | Gnd |
| AC1 | SEL2 | AC2 | Gnd |

| AE1 | DEN0 | AE2 | WD1 |

For the TMA11 and TMB11, delete the "MAN CLR L", and re-name "DEN0" and "DEN1" to "DEN8" and "DEN5" respectively.
