Re: interfacing a WILCO Trackball to serial port

: Take a look at the following web-page: : http://www.mameworld.net/pc2jamma/trackball.html : It should work if the Wilco trackball has a standard 5v active low interface (there are ways to solve it even if it is active high, se my previous postings about KE72-T, trackballs and active high or low, using my old nick "Rob"). The KE72-T from Hagstrom, the HAPP trackball interface and the new generic trackball interface from Andy (the inventor of I-PAK) are all alternatives to a hacked mouse solution. Se my previous posting "Trackball and spinner and general interface". : / EmuMannen : : : Has anyone successfully interfaced a Wilco 3" trackball : : to a serial port or is there any instructions somewhere. : : there are 6 wires coming off it. a ground,a positive, : : and four data I assume. The paper that came with the : : unit said to switch the grouped wires if the direction : : needed to be switched. It grouped two wires for up : : down and two for left and right. If anyone can help I : : could use it. Thanks : :
