IBM Model B 6580 Displaywriter 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. Added a solenoid to give this the oomph it was denied by IBM.

EDIT: Picked up a very cheap Selectric II, and now this has Selectric caps on most of the alphas, and is wearing a cool black IBM badge.

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