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 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.
HARDWARE
NetBSD includes machine-independent TURBOchannel drivers, sorted by device type and driver name:

tcds PMAZ-DS, PMAZ-FS, PMAZB-AA and PMAZC-AA dual-channel SCSI adapters
Network interfaces

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