TS(4) BSD/vax Kernel Interfaces Manual TS(4)NAMEts — 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

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
