The TM03 magtape controllers is a MASSBUS device controller, used with 1/2" magtape drives; supported drives include the TE16 (45 inches per second), TU45 (75 IPD) and TU77 (125 IPS). It can handle 800 bits/inch (NRZI) and 1600 bits/inch (PE - Phase Encoded).
It can control up to 8 drives, although the TM03 and drives count as only a single MASSBUS entity. The TM03 controller connects to all the drives over a 'slave bus'; all the drives are identical (unlike in the TM11/TU10 system.
Implementation
The TM03 is implemented as a set of larger custom boards, all of which plug into a custom hex-high nine-slot system unit (for a BA11, etc box). The modules include three hex-size boards, six quad-size modules, and six dual-high modules.
The hex modules are:
- M8933 - Tape Control Common Mode
- M8909 - MASSBUS Interface (the documentation refers to both the M8909, and M8909-YA)
- M8906 for use with a PDP-11
- M8915 for use with a PDP-10 and TE16 or TU45
- M8915-YA for use with a PDP-10 and TU77
The quad modules are:
- 3 x M8901 - Data Sync - PE
- M8901-YA for the TE16
- M8901-YB for the TU45
- M8901-YC for the TU77
- M8932 - Tape Control - PE
- M8934 - Tape Control - NRZI
- M8934 for the TE16 and TU77
- M8934-YA for the TU45
- M8905-YB - Maintainence Register
The dual modules are:
- M8937
- M8908-YA
- M8908
- 3 x M5903 or M5903-YA
The first three are the drive slave bus intergface; the last three are the MASSBUS interface.
