Got this last week among a stash of others. I know KeyTronic never used microswitches but still wanted to pop off a keycap from this one to see what was underneath. Well, I failed. It seems the keycaps are connected in some sort of matrix. When you pull on one, only the bottom part comes off and tilts upwards but the top part is still firmly connected to that plastic layer underneath. I've added some photos - has anyone seen this? As the board was still manufactured in the US rather than Ireland like some other ISO DIN KeyTronics I've seen, I assume it's very early production.
If anyone collects this sort of thing let me know - you can have it for shipping costs from Germany.
