Hardware Description

The 3P+S Input/Output S-100 board was designed to meet all the I/O needs of most early 8800 system users. For example, one teletype and two TV typewriters with keyboards could be operate simultaneously with the 8800 through only one 3P+S. Similarly, one RS-232-C modem, a teletype, and one TV typewriter plus another parallel data device could all be interfaced with one 3P+S at the same time.
