the black bars you see are jumpers that can be moved to set faults. Then you use all kinds of tools, Logic Probes, Pulsers, Current tracers, or even signature analyzers to find the error.

I first came into contact with these back in 1987, when I learned to repair computers, and I considered it a pretty nice kit back then.
Schools would typically buy in a whole set of these, and either make some training-manuals themselves, or they would buy thick lab-manuals from HP for this kit.
I think I still have the manual I used, and may scan in a page or two to show how thorough it was.
From what I have heard, many schools have just thrown these away as they were no longer in use and only took up space, so they're not exactly flooding the vintage-computer markets. If you collect computers and computing-memorabilia, and get the chance, GET IT!
