Abstract
There is disclosed herein an apparatus for computerized real time verification of the correctness of pin locations for wire wrap connections made by human operators in constructing or upgrading computer backplanes. A suitably programmed microprocessor operates from a data base consisting of the information from a wire list drawing fed into the microprocessor's memory from a cassette tape record. The microprocessor is linked to the backplane to be verified and to the hand operated wire wrap gun serving as the test probe by a uniquely designed Wire Check System Interface. Both wire adds and wire deletes may be made. The microprocessor serves to check the operator's badge number for proper authority, bootload the data base, find the sequence of wires to be added or deleted, display the addition or deletion data on a CRT by identifying the "from" and "to" pins, and to verify the correct placement of the wire wrap gun by the operator by lighting a red or green LED and sounding an audible alarm on red when an index/test strip switch is activated by the operator. Printed reports of wire check errors are also generated. In the preferred embodiment, use of the computer aided wire wrap opera…
