This is interesting to me, include me on your list too please.

I think we can assume the hardware in the 364 would have been the same as in the Magic Voice cartridge, which incidentally was on eBay a few days ago. The plus/4 may never have had speech, but it got the "fast" disk drive system originally planned for the '64 - I'm sure the planned peripheral for the other expansion line (CP/M being the first) is what eventually became the 1551. You win some, you lose some :-)

As for the numeric keypad, well - as far as I'm aware (and please check these, ROM disassemblers), there's no routines in the kernal for seperate keyboard hardware (whereas the $fd20 stuff is still there), so I suspect the keys on the number pad were wired to the same points on the matrix as the ordinary number keys, etc. This technique is used for the multiple Control and Shift keys in the plus/4, so I think it would have been extended to cover the whole number pad.

Richard.
