Interface allows microcomputer to test parallel buses

If problems arise in the manufacture or maintenance of a wire-wrapped computer bus, eyeballing or even using a multimeter proves both uneconomical and inefficient for resolving open and shorted connections. It is shown that a tester based on a microcomputer, an interface board with a power supply and plugs dedicated to a particular bus (e.G. Unibus, multibus, s-100, z-bus, etc.) can overcome these problems. Providing the microcomputer with suitable software allows this small test system to learn the structure of a particular bus from a known-good bus. From then on, this tester can run diagnostic tests to pinpoint open and shorted connections.
