Major SX-64 acquisition (and some other stuff)

Today at work what I was really hoping to happen did happen. I was given three working Commodore SX-64 machines. We are in the process of consolidating to fit the lab into a smaller space and they're throwing away tons of stuff. There is a fourth SX-64 still in occasional use, and I was able to get these machines by promising that if the one at work fails I will bring in one of these to use in it's place. So I have all three machines, but they're essentially 'non-transferrable' until we come up with a replacement for the one on a fixture. Which will probably happen eventually (and then I'll probably get a fourth SX-64.) I also got a whole pile of mid-years DOS clone machines and misc. The three most interesting machines are 1. An 'Expansion Box' chassis, i.e. a passive backplane with a card in it and a card with a wide cable on it, meant to plug into another chassis that has the CPU. and 2. An old Wyse 386 machine that has a fairly curious construction. The CPU is on a card plugged into a 'passive' backplane, and the Hard Drive controller plugs in planar to the backplane. The HD controller appears to be a fairly standard 'AT' type controller. This machine also has no 'standard' PC-type keyboard connector. There's a snap in connector similar to a telephone connector, and on the same bracket area, a 9 pin connector. There's a VGA ISA card plugged into the system, but is it possible the machine would work with a serial console? The 'CPU' cards plugged into the backplane are complex, with a bridge connecting two of them on the opposite side, parallel to the backplane connectors. 3. (probably least interesting) An ALR 386 system. The big classic 'full AT' case and motherboard. The CPU is a 386DX-16 and it also has the '387 coprocessor. Anyhow, I consider it all a fairly good 'score' though the SX-64's greatly eclipse all the PeeCee boxes.
