IBM Displaywriter 6580 Keyboard

The White Whale! Acquired from eBay in nearly perfect condition, this keyboard only needed a quick wipe down of the PCB with isopropyl alcohol to be in good working order. Converted with a self-assembled TH-XWhatsit controller. I've got a solenoid on order to give this the oomph it deserves.

I used the original card edge connectore
Beamspring switches - interestingly the previous owner used large o-rings to support them rather than replacing the degraded foam
