Specifically, we need a keyboard routine which would toggle the and keys to allow one-finger typing, and a software patch which would allow a trackball to be used as the default pointing device instead of the mouse. The ideal solution would be to find a trackball which is electrically compatable with the existing optical mouse. However, I have been in touch with Mouse Systems, and they do not make such a device. The optical mouse which they manufacture for Silicon Graphics is a special OEM version which employs a RS-423 interface, and their trackballs are all RS-232. They were very congenial, however, and offered to consider such a product if we were willing to guarantee an initial purchase of about ten thousand units... Thanks, but no thanks. So I am seeking the assistance of the SGI engineering and/or user community, and would appreciate any help you could provide. Thanks!! ......................................................................... : Dale Olson | : : Systems Engineer | : : Silicon Graphics | "Workin' on mysteries without any clues..." : : Timonium, MD | : : 21093 | (301) 561-8038 VM 8480 : .........................................................................
