# DESCRIPTION

The `wax` GSC bus controller is a version of 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 HP 9000/712 models).
