Description

Note from donor: "Almost all those pieces of hardware have at least one RS-232C serial port. RS-232C was designed to provide point-to-point communication, and it requires some central manager "box" to produce a network. But, with as little as one diode per port, two resistors for the ends, and a -12 Volt source, you can turn RS-232C into ULCnet, the Ultra-Low-Cost Network."
