For some applications the SKC2000 hardware includes a system configuration in which a PDP11
minicomputer is connected to the CCU and acts as a front end to the SKC-2000 for peripheral
devices connected to the PDP11. The hardware and PDP11 software have been constructed so that
they are transparent to the user in regard to operating the CCU. The use of the PDPll is not further
described herein.
