Yes! I did it! All by myself (almost)! I have a program for interfacing the trak-ball to Basic (or anything else). An assembly routine, which safely resides in page 6 and uses the pokey timer interrupt, tracks the trak-ball and places its position in two bytes in page 0, where it can be read by PEEK's. The regular interrupt, plus the handler, run continuously, and only seem to slow down main execution time by 5% or so. I like the trak-ball, not only to replace the joystick, but even more so, to replace the paddles (only sideways motion is used). Would be happy to share. -Stan
