In Reply to: I've been talking about this for awhile... mechanically interface the spinner the trackball (text and pics!) posted by Tom61 on September 05, 1999 at 18:20:56:
What interface are you using? The serial port (e.g. mouse)? Wouldn't an electronic interface be easier? The signal from a trackball and the signal from a spinner are identical. You'd need to solder only 3 wires and a switch to join a spinner to a trackball. But even that's not necessary. A trackball and a spinner can plug into different serial ports and can share control of a single pointer.
