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).

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
AD1 AD2 WD0
AE1 DEN0 AE2 WD1
AF1 DEN1 AF2 WD2

BP1 RD7 BP2 7CH
BR1 RDP BR2 EOT

BT1 Gnd BT2 LRCE
BU1 BU2 LRCS
BV1 MAN CLR L BV2 Gnd

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