Abstract

The proliferation of personal computers has engendered considerable testing of compatible keyboards for attachment to the computers. The testing is done to qualify new technologies for use and to monitor the quality of existing designs and product offerings. The monitoring of keyboard outputs is a critical aspect for all compatible keyboards to be attached to a given personal computer. Existing test boxes built with hand-wired connections and incorporating analyzer logic circuits are often used for this purpose. In each case, a special interface circuit is constructed for each keyboard unit to convert the keyboard signals into an appropriate format for communication with the analyzer device.
