Abstract: A radio includes a receiver circuit, a microprocessor, an input/output (I/O) port, at least one switch for configuring the I/O port, an audio amplifier coupled to the receiver circuit and to the I/O port, an audio frequency transducer coupled to the I/O port, and a power supply coupled to the I/O port, the receiver, the microprocessor, the at least one switch, and the audio amplifier. The at least one switch is coupled to the microprocessor. The audio frequency transducer is selectively coupled to the audio amplifier through the I/O port and the power supply is selectively coupled to the I/O port to permit activation of the audio frequency transducer by a signal coupled from the audio amplifier through the I/O port and to provide access to the power supply through the I/O port.

Abstract: A font storage system for use in a typesetter having an electronically controlled character imaging device. The storage system, which preferably includes a floppy disk, has digital information stored thereon defining each character to be typeset by at least two outlines on a normalized X-Y grid. The digital information defining each character includes (1) digital numbers defining the X and Y coordinates of the initial start points of the outline and (2) digital numbers defining a plurality of straight line vectors extending successively along the character outlines. Each vector has a first digital number representing the X coordinate distance and a second digital number representing the Y coordinate distance from one end of the vector to the other.
