ts — TS-11 magtape interface

controller zs0 at uba? csr 0172520 vector tsintr
tape ts0 at zs0 drive 0

The TS-11 combination provides a standard tape drive interface as described in mtio(4). The TS-11 operates only at 1600 BPI, and only one transport is possible per controller.

ts%d: no write ring.
An attempt was made to write on the tape drive when no write ring was present; this message is written on the terminal of the user who tried to access the tape.
ts%d: not online.
An attempt was made to access the tape while it was offline; this message is written on the terminal of the user who tried to access the tape.
ts%d: hard error bn%d xs0=%b.
A hard error occurred on the tape at block ; status register 0 is printed in octal and symbolically decoded as bits.

The ts driver appeared in 4.1BSD.

May hang ungracefully if a physical error (non-data) occurs.

The device lives at the same address as a TM-11 (tm(4)); as it is very difficult to get this device to interrupt, a generic system assumes that a ts is present whenever no TM-11 exists but the CSR responds and a TS-11 is configured. This does no harm as long as a non-existent TS-11 is not accessed.
