I think this came from some company that built (or repaired?) hard disk drives. The cards and power harness had been removed, but the case has a nice 7-slot S-100 backplane and a pair of especially nice Mitsubishi M2896 8" floppy disk drives. Back around 2016, I built a new power harness and fitted it with a #Compupro #S100 board set.
The little rack it's in flips right over with the computer rolled out on its rails, so I made a pair of legs with 80/20 extrusion. They're a bit cumbersome to use, but they were easy to make.

Long term goal in hacking the Teletek #S100 hardware is getting the front panel speaker to make noise.
According to this:

The 741 op-amp to drive the speaker can be run directly off the unregulated ± 18V that the S100 bus provides!
I wish the wire wrapped mess that is the front panel controller at least matched the schematics for it, but it doesn't.
It's a latched buffer, then (???) to 741 to speaker. Wire up the 741 right, then I can figure out what (???) is?
Ok so a standard circuit board is 1.57 mm or 0.062 inch thick, and a S100 circuit board is 5 inch x 10 inch.
So I've ordered some 8" x 12" plastic sheets that are 1.5 mm thick, and a pair of 80mm 12v fans to build a fan card to help cool my S100 CP/M box!
