At 02:03 PM 4/10/2004, nathan, had this to say : >If I upgrade my 280c w/ a 2300c mobo can I keep my trackball? Or do I have >to go to the trackpad? No worries, you can still use the trackball! I broke the ribbon cable attaching the trackpad in my 2300 so I had to swap it out for a trackball. Looks odd, but it works! This is one of the great features of the Duo line. Most parts are swapable. :) Sincerely, R.
