Sb: #Trackball InfoFm: Frank Hausman 71251,2002Atari TRAKBALL: In TRAKBALL mode. Here's what I've learned about thedata from TRAKBALL mode: Bit Function 3 Clock for vertical motion 2 Direction: 0=up, 1=down 1 Clock for horizontal motion 0 Direction: 0=left, 1=rightIt's a good idea to sample the trackball VERY FREQUENTLY to avoid missingclock transitions, and causing non-linear responses.
