Subject: Re: Commodore keyboards and PCs
Technically, C=Key is designed to work inside a perfectly functional C64
or C128. If the 64 is on, it will convert PS2 inputs to C64 keypresses
(in combination with the current 64 KB). If the 64 is off, it will
convert the C64 KB actions to PS2 KB events.
I was thinking... isn't the PS/2 keyboard protocol simply a
low-bitrate serial protocol at TTL levels? Could the 6510 then not
act as the microcontroller?
That is, why not connect the user port to the PS/2 port and run a
program on the C64 to send the keypresses to the PC?
Of course, this runs dangerously into the direction of a "why use an
emulator if you have the real thing" kind of debate... :-)
