[vcf-midatlantic] What's wrong with my program experiment?

[Evan Koblentz]

Disregard my entire post from earlier today. :)  Here's a smarter post:

I'm using the Apple joystick A2M2002.

Ran this test program:

10 X=PDL(0):Y=PDL(1)
20 PRINT X,Y
30 GOTO 10

The four corners report correctly (0,0; 0,255; 255,0; 255,255) but when 
the joystick centers it shows 130,89. If I adjust the trim knobs then 
the corners would be wrong.

How do I fix this?
