  SpaceSpuds (3D) supports Standard IBM Joysticks in the second mouse
port.  The RKM suggests approx. 470K ohm pots for analog joysticks,
but using pots with this value will yield readings from about 0..49.
The range should be from 0..255.  We did some testing and found 1
Mega ohm pots will generate the necessary range (approx. 470x2 =
940).  Perhaps Dale or Bob can tell us why this is so...  Anyway,
before analog joysticks are to become popular on the Amiga, custom
joysticks with 1M pots will have to be produced.  I have a Gravis
IBM analog joystick working with SpaceSpuds, but with a range of
only -24..+24.  The circuitry in the 500s generate spurious readings
with even less range; with 2000s, a more stable range abliet less
than a 1000.  Hopefully these problems will be remedied and a major
joystick manufacturer will build special joysticks for the Amiga.
