context_page_description: The BeBox is a dual CPU personal computer, briefly sold by Be Inc. to run the company's own operating system, BeOS. Notable aspects of the system include its CPU configuration, I/O board with "GeekPort", and "Blinkenlights" on the front bezel.
  The BeBox made its debut in October 1995. The processors were upgraded to 133 MHz in August 1996. Production was halted in January 1997, following the port of BeOS to the Macintosh, in order for the company to concentrate on software. Be sold around a thousand 66 MHz BeBoxes and 800 133 MHz BeBoxes.
  BeBox creator Jean-Louis Gassée did not see the BeBox as a general consumer device, warning that "Before we let you use the BeBox, we believe you must have some aptitude toward programming – the standard language is C++."
