Abstract

A nonvolatile random-access memory (NVRAM) connected to a 5085 control unit may be used to provide an output signal produced by a unique series of key-presses on the 5080 graphics puck which signal places the 5085 control unit (C/U) in an operating state. The unit is locked in an inoperative state until this unique password has been entered.
