.Sh NAME
.Nm tc
.Nd TURBOchannel expansion bus driver
.Sh SYNOPSIS
.Ss alpha
.Cd "tc* at tcasic?"
.Ss pmax
.Cd "tc* at mainbus0"
.Sh DESCRIPTION
The
.Nm
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.
.Pp
Your system may support additional
.Tn TURBOchannel
devices.  Drivers for
.Tn TURBOchannel
devices not listed here are machine-dependent.
Consult your system's
.Xr intro 4
for additional information.
