I've hunted through the places where any separate manual for CHIPTEST ought to have been if it ever existed but have unfortunately drawn a blank. I can still scan the main manual if desired, although as stated, CHIPTEST is conspicuously absent from that manual.

One of the features of CHIPTEST is that it allows you to take an existing chiptest profile, modify the parameters and save it as a 'user' part. (You aren't allowed to make changes to the 'built in' tests). If you load up an existing chiptest profile, say for a Hex Inverter, and look through the profile and understand how it works (assert input states pattern 1, look for expected output states, assert input states pattern 2, look for expected output states) and then go on to something more complicated like a counter (7490?), that will illustrate how to generate an input clock pulse, and so on and so forth.

Generating a test sequence for a micro peripheral IC such as the 8255 (already provided in the standard CHIPTEST parts set) or a Z80-PIO, or Z80-DART must take a great many individual test steps.
