I've owned many machines in my day, but the one that had the best keyboard of them all was probably the Tandy 1000TL that came out in 1989. It was something of a Model M clone, and had a solid and tactile feel. I have no idea which switches it used, but looking at videos of some Topre-based boards, it seems like it had a similar mechanism as best I can recall.

Thanks.
