I really do

As a collector of old computers I have keyboards everywhere. Sun typ 3, 4, 5, Ibm terminals, Wyse, VT 1xx, 2xx, 4xx, HP700 terminals, Macs, PC, RS6000 (ok, they are PS2 but black with a cool IBM logo), SGI etc etc. Easily > 50 keyboards taking up space.
And when I find a cool computer the keyboard is either missing, broken, dirty as hell or has one or several keycap missing.
Anyways, I didn't join to complain. One of my favourite computer from the 70-ies has a KeyTronic cap/foam keyboard and I wanna design a Cherry MX drop in replacement keyboard and this seems like the right place to ask question.
