The TS11 controller was a UNIBUS magnetic tape controllers from DEC; it was part of the TS11 Subsystem, along with a TS04 Tape Transport. It used DMA to transfer both data, and 'command packets', which are commands to the device to perform various functions, stored in main memory.
The TS11 controller is a hex card, the M7982, which plugs into an SPC slot. Two DIP switches, E90 and E34, configure the controller's bus address and interrupt vector (respectively). The controller is designed for PDP-11 and VAX computers with a UNIBUS.
Contents
Device registers
The TS11 contains only three registers in its own hardware; two are read-only and write-only (respectively), and share the same bus address:
| Register | Abbreviation | Address |
|---|---|---|
| Data Buffer Register | TSDB | 772520 (write) |
| Bus Address Register | TSBA | 772520 (read) |
| Status Register | TSSR | 772522 |
(Addresses are given assuming the TS11 is configured to the standard base address, 0772520.)
