The TS04 Tape Transport (referred to in most DEC documentation as a TS11 tape transport), was the magnetic tape drive of the TS11 Subsystem. It contained an integrated formatter, which used a custom microprocessor for overall control. It communicated with a TS11 controller over a serial bus. The transport was packaged with its associated power supply in a standard 19-inch rack mountable frame.
Reading and writing are performed at 45 inches per second, and data is recorded at 1600 bits per inch, using PE encoding. Use of ANSI standard format recording allows data to be transferred easily between computer systems.
Details
The formatter and on-board electronics consisted of a number of PCBs, some mounted on the main deck-plate of the transport, and connected to other boards by harnesses, but most plugged into specific, numbered slots in a custom backplane in a logic rack:
