The PC-12 and PC-89 provides the expansion and interface capability which was previously unavailable for Heath computers. The popular 8255A Programmable Peripheral Interface (PPI) chips are utilized to provide plug-in connection for a multitude of peripheral devices such as voice and music synthesizers, printers and plotters, control and data acquisition equipment, etc., all without jeopardizing the integrity of the computer system. The perpetual clock/calendar maintains an absolute time and date reference without system power applied. Extensive documentation and support disk software is included. There has never been a better method of extending the capabilities of your computer system.
