The 66MHz BeBox began production in 10/95 (it was introduced at Agenda '95, to a standing ovation) and was manufactured until 12/96. The 133MHz BeBox began shipping in 10/96, and ended when Be announced that we would discontinue hardware production, on 1/30/97.
Over that time, Be sold around 1,000 66MHz BeBoxes and a little over 800 133MHz BeBoxes. Most of these went to developers, with the rest going to unusually discerning and technologically savvy individuals. ;-)
