The Amstrad PC1000's and the PC2086 were IBM compatible (they did have some
non-standard hardware - the 1512 had 16-colour CGA, the 1640 could have it as
an option, both the 1512 and the 1640 have NVRs to save settings like a CMOS)
and they had an 8086 processor - some (like my original 1512) have the slightly
faster NEC V30 - it has some 286 instructions as well - fitted instead. One
thing I've always wanted to try was putting an 8086 chip in place of the 8088
on an original PC - IIRC they have the same pin-out.
Of course, there was always the PC-XT286 - this is about the time I get
confused and run away screaming.
Re: switchable keyboards, I had an XT/AT switchable on my old Elonex 286. Set
it to AT it works, flick over to XT and the controller goes mental - upon
boot-up it beeps and flashes the LEDs twice a second, if the thing is already
running and you flick the switch as soon as you press a key it does the same
thing. Pity it's dead now...
