   I do have a couple left but I'm not parting with them :-) That's why I decided to put in a plug for your auctions. You're right, they're worth a lot more than $90! I sold a couple on E-bay for ~$130 and if you're selling the ones that you got from me they've all been cleaned, tested and repaired including replacing the missing power cords with original HP cords, replacing all the missing straps so that they'll stand up like an A-frame, replaced the broken snap fasteners, etc. And they included all the manuals (or at least NEW copies of them).

   Yeap, and it's a lot easier to work with and more reliable than the cheap sockets and jumper wires that HK uses. If I want to use the HK style breadboard, I can jumpered from a plug over to a full size breadboard.

   sheesh, Every other microprocessor book that I pick up has interfacing information. The PM includes stuff like how to use Logic Analyzers, logic probes, logic pulsers, current tracers, signature analyis that's seldom covered elsewhere. I guess which one is best depends on wheather you want to design computers or fix them!
