Well I bid and got 2 Siig Minitouch keyboards (
Here). The cords were cut and one of them was missing the F1 key cap. When I got them, they were otherwise in great shape and very clean. There was only some minor smudges on the cases which cleaned up easily with some 90% isopropyl alcohol. When I opened the keyboards, I found that the cut cords were attached to a 5-pin molex connector.
I took the pins out of the molex connectors and recrimped a couple of donor cables onto them. With the help of a multimeter, I figured out which wire was which and reattached the molex connectors. The keyboards worked 100%! Though I still prefer the buckling springs of my trusty model M's, the white ALPs are fun to type on. Now I gotta find a F1 keycap. I thought I had a source but alas, no.
