NAME
tc -- TURBOchannel expansion bus driver
SYNOPSIS
alpha
tc* at tcasic?
pmax
tc* at mainbus0
DESCRIPTION
The tc driver provides machine-independent support for the DEC TURBOchan-
nel expansion bus found on all DEC 5000-series machines with MIPS and DEC
3000-series with Alpha processors.
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.

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