Abstract
A teleprinter terminal includes a keyboard and a printer, each of which is operated by means of a self-contained microprocessor, and a third microprocessor is programmed to handle the communications. The three microprocessors are interconnected to operate in a four-bit bus manner wherein communications between the processors is done in bytes but the four-bit bus forces the byte to be transferred in two, four-bit exchanges. One four-bit bus is used to connect the communications processor with the keyboard processor and with the printer processor and a second four-bit bus is used to connect the keyboard processor and the communications processor.
