Probably a silly thing. Not that i don't find it useful playing with
a joystick, but we've inherited one of IBM's pitfalls. To request the
joystick's position, you have to send a pulse out of port 0x200, thus
starting a timer (mono-flop, one channel of a NE556), then you have
to query port 0x200 regularly to measure the time 'til the mono-flop
falls back. Kinda CPU hog, not much good to run under unix, i'm afraid.
