NAME
tc - TURBOchannel expansion bus driver

SYNOPSIS

  alpha
tc* at tcasic?

  pmax
tc* at mainbus0

  vax
tc0 at vsbus0

DESCRIPTION
The tc driver provides machine-independent support for the DEC TURBOchannel expansion bus found on all DEC 5000-series machines with MIPS, DEC 3000-series with Alpha processors and VAXstation 4000 machines with the optional TURBOchannel adaptor.

Your system may support additional TURBOchannel devices. Drivers for TURBOchannel devices not listed here are machine-dependent. Consult your system's intro(4) for additional information.

HISTORY
The tc driver first appeared in NetBSD 1.1.

BUGS
The tc driver makes poor use of interrupt priority on the 5000/1xx series systems.
