.Sh NAME
.Nm wax
.Nd GSC bus controller and I/O subsystem
.Sh SYNOPSIS
.Cd "wax* at mainbus0"
.Cd "wax* at phantomas?"
.Cd "gsc* at wax?"
.Sh DESCRIPTION
The
.Nm
GSC bus controller is a version of
.Xr hppa/lasi 4
with limited functionality and no additional devices on the crystal.
It is mainly used as a GSC bus controller for additional onboard devices
(e.g. 2nd RS232 or HIL) and sometimes add-on cards (such as a TR-9000
card for the
.Tn HP 9000/712
models).
