And this part is somewhat funny, too, because the PS/2 connector layout is
capable of having both devices share the same bus (there's two unconnected
pins, which some laptops use to provide alternate CLK/DATA signals).

If PS/2 mice used the unconnected pins rather than the same CLK/DATA pins as
the keyboard, all machines could simply have two connectors using all six
pins and you'd be able to plug either device into either socket.

In other words it should work like Apple's ADB (Apple Desktop Bus) ports 
do (did until they moved to USB).  I really miss those ports.
