For a while I have been contemplating the Apple II joystick...I'd like some
feedback on these ideas:

Reducing the range of Apple joystick potentiometers from 150Kohm to around
100K or so:  Would this allow people to use the joystick for accelerated 8-bit
games on the IIGS?  Would this allow somewhat improved joystick response for
native mode GS games?  I'm assuming that this would allow for quicker draining
of the capacitor in timing the analog inputs...sorry for the garbled
terminology. 

ADB joysticks:  With the problems of using those old Apple II joysticks on a
GS, how about making new ADB devices that could still be compatible with old
software?  The IIGS keyboard is an ADB device, yet old software that tweaks
the old keyboard locations $C000 and $C010 still work.  In emulation, the ADB
joystick would act like an old 150Kohm one.  In native mode, the joystick
could react near instantaneously, simplifying game loops and so forth.  Better
yet, the Apple II gaming world could AT LAST have 2 joysticks that didn't
intefere the heck out of each other.  Or even 3, 4, 16 joysticks!  Bwa ha ha
ha!

Question:  How much does it cost to make a device ADB compatible?  Are these
parts availiable solely at the whim of Corporate Apple?
