Hardware: Joysticks, why GEOS doesn't support them

Joysticks on the PC are incredibly hard to deal with in a multi-tasking
operating system, unfortunately, as they aren't autonomous. Most devices,
even if you have to ask them what their position is, work pretty much on
their own.

Joysticks require the software to poke something and then sit in a very small
loop of code counting the number of times through the loop until a value put
out by the joystick changes. While it's doing this, the software cannot do
anything else.

Even on the Zoomer, it's not actually a joystick, but a four-switch keyboard.
2.0 does come with a keyboard-driven mouse, however, which allows you to use
the arrow keys on the keyboard to move the pointer around.
