Abstract
A self-test monitor and diagnostic apparatus which includes a test step counter, an error comparator apparatus, which may be a memory device loaded so as to predict the proper state of each of the lines to be monitored at each test step and which functions to detect any difference between what should be occurring at that test step and what is, in fact, occurring on the monitored line, and an error localization network which translates the detected errors into a displayable code for maintenance isolation.
