ABSTRACT:
A peripheral unit is provided with a control panel that includes a plurality of indicators, each indicator displaying to a user a state condition of the peripheral unit. The control panel also includes a user operable key. A "state" circuit is responsive to a functional state of the peripheral unit to cause the state indicators to manifest a selected one of a set of state conditions. A controller is provided for initiating peripheral unit operations. A state logic machine is responsive to each manifested state of the set and user actuation of the key, to cause the controller to initiate a peripheral unit operations, that operation uniquely related to a state manifested by the indicators.
