NAME
tcTURBOchannel expansion bus driver
SYNOPSIS
alpha
tc* at tcasic?
pmax
tc* at mainbus0
DESCRIPTION
The tc driver provides machine-independent support for the DEC TURBOchannel 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.

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.
