True enough. I have even bought some switches and non so great Cherry keyboards to harvest keytops.
About 10 WY-30 keyboards in so-so condition showed up for about $7 ea, so i'll probably just go with
that, since they seem to be the least desirable (next to WY-50) for the mechanical collectors.

Televideo was pretty consistent with their serial keyboard protocol and voltages, Qume.. not at all.
I've identified at least 4 different styles of 4-pin connector keyboards using either 12 or 5 volt power.

Then, there is ADDS, Hazeltine, Microterm, DG, Freedom, ...
