Initial thoughts on the IBM joystick that I have.
John Stewart CRC Canada.

1) install the sound modules /lib/oss/sndon

2) install the joystick driver

	insmod /usr/src/packages/joystick/joystick.o
	insmod /usr/src/packages/joystick/joy-analog.o

3) test it... jstest /dev/js0

------------------------------------------------------------

Base switches to left left.

Axes 0 : l/r movement.
Axis 1 : f/b movement.
Axis 2 : left thumb wheel.
But  0 : index finger button - RAPIDLY CYCLES.
But  1 : thumb button.
But  2 : left button on top of stick.
But  3 : right button on top of stick.

left  base switch controls whether the stick centre 4-way switch
does anything or not. (in conjunction with left thumb wheel.

Right base switch controls whether index finger trigger 
is continuous or not.

To make it work, emulate "fly" mode.

no buttons pressed:
	- left/right - rotate left/right.
	- for/backward - translate forwards/backwards.

left button pressed:
	- left/right - translate left/right.
	- for/backward - translate down/up.

right button pressed:
	- left/right - rotate "sideways".
	- for/backward - rotate up/down.
