Abstract
A calculator system is provided using a stored program data processor and an audio message subsystem to process digital information and to provide audio messages for operator interaction. The calculator system utilizes a digital data processor to execute program routines to process digital information and to communicate with an operator using audio messages. Digital message information is stored in a digital memory and is accessed in response to operator generated signals to provide audio messages.
