I believe the hardware _is_ identical. It would be amusing for somebody
to do a driver so that you could plug a second keyboard into your PS/2
mouse port. Quite what you'd do with it then, I'm not sure, but I imagine
people will think of something, given a sufficiently sick imagination. I
suppose buying VGA cards and PS/2 mouse interfaces is cheaper than buying
computers, and you could theoretically devise some scheme to pair up
screens and keyboards with virtual consoles...
