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

AJ1 WXQ AJ2 WD4
AK1 FWD AK2 WD5
AL1 RWD AL2 WD6
AM1 WRE AM2 WD7
AN1 Gnd AN2 REV
AP1 Gnd AP2 CINIT
AR1 Gnd AR2 SET
AS1 Gnd AS2 WDR
AT1 Gnd AT2 PEYN
AU1 AU2 WFMK
AV1 AV2 Gnd
BA1 RDS BA2
BB1 SDWN BB2 Gnd
BC1 TUR BC2 Gnd
BD1 Gnd BD2 WRS
BE1 Gnd BE2 CRCS
BF1 RD0 BF2 RWS
BH1 RD1 BH2
BJ1 RD2 BJ2
BK1 RD3 BK2 BOT

BP1 RD7 BP2 7CH
BR1 RDP BR2 EOT
BS1 FMK BS2 CRCE
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.
