The SlotTrak program functions as a lap counter and lap timer for any scale slotcar track. It will operate on any 1 to 8 lane track. In addition to simple counting and timing, it will run various types of races complete with lane rotations and optional power control to the track. The timing resolution is 1 millisecond. Results are saved, and can be recalled for viewing and race report generation. The parallel, serial, joystick port and now the TrakMate Windows hardware may be used for lane input. SlotTrak is also compatible with Scalextric's RMS hardware. The parallel port, serial port, or TMW hardware may be used for track calls. The parallel port, serial port, TMW hardware (track power) or phidget cards (individual lane or track power) may be used for power control. Runs on all versions of Windows from 95 up - including XP.
