NAME
tc —
TURBOchannel expansion bus
driver
SYNOPSIS
alpha
tc* at tcasic?
pmax
tc* at mainbus0
vax
tc0 at vsbus0
DESCRIPTION
Thetc 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.
