I have GFA v2.0 and am interested in using the joystick port (1). Does anyone
know what the trick would be. I don't want to use for a joystick, I want to
use it for the Atari CX85 Keypad (an old item, I know!). Recalling the use
of the standard Atari joystick on the 8-bit series, a number was returned
indicating the position of the joystick. The keypad returned numbers in a
very similar way on those machines, and I would like to find out if there
is a command I'm skipping over or a location that I could Peek?
Also, can anyone suggest a good ST manual similar to Compute's Memory Map set
for the 8-bit series. I've tried quite a few bookstores, computer stores,
etc., and cannot find a single Atari ST book out there.
Thanks!

I don't know why people keep talking about GFA BASIC 2.0 as if it couldn't use the joystick. Here's how to access the port: spoke &hfffc02,&h14 ; turn off mouse while whatever loop a = peek(&hfffc02) print a ; a returns the value of the joystick port. ; experiment to find the exact values. . . code . spoke &hfffc02,&h8 ; restore the mouse before exiting program. That's it!
