In the thread about Warmouse's unauthorized and many-buttoned OpenOffice mouse, Don Simpson points to ProHance's illustrious original, the PowerMouse 100, which features no fewer than 40 buttons! It requires DOS 2.0. [AtariMagazines] ProHance Technologies in Sunnyvale, CA also made 3-, 12-, and 17-button mice.
Makes you appreciate two buttons and a scroll a whole lot more, eh?
