Re: I've got the real thing
Oh yeah, the original PET's "electronic till" keyboard was not awesome. Ours were more conventional, somewhat similar to the VIC-20/C64 though with different symbols and profile compared to what I recall of their smaller siblings.
I think most BBC Micros used the Futaba keys. They're the ones I prefer, anyway; nice linear clacky action. Actually I preferred the Electron's keys (same as the Master IIRC) but they apparently have some issues with longevity. That said, my Electron died before its keyboard did. I recall there was a great deal of snobbery about keyboard types back in the day with the Dragon's being lambasted in comparison, but having tried out both more recently I honestly can't tell much difference at all between the BBC's Futabas and the Dragon's Hi-Teks. The BBC had a nicer key profile (which nobody mentioned; and is a very subjective matter anyway, both having good quality keys especially compared to most of today's offerings) and a more comprehensive layout, which again (almost) nobody mentioned, curiously...
I find that the contemporary Cherry MX Red switches have a not entirely dissimilar feel and sound but I prefer them with "retro" key-caps: the old-style spherical (i.e. bowl-shaped) keys are nicer IMHO than the cylindrical profile which has been pretty much the standard since the IBM PC happened. I'm slightly loath to make glowing comments about Cherry MX keys which is entirely based on my hatred of their tactile switches, which seems a bit unfair and probably slightly silly.
