Hewlett Packard 5036A Microprocessor Lab

The big(well, rather small, really) secret of this trainer.
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.

Now, THIS is a real find. It is a HP-made Microprocessor-trainer built into a suitcase. Not only does it do a very good job of explaining how a computer is built, but it is also a great machine for learning how to repair one as the PCB is littered with small jumpers that can be moved around to create faults.

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!
