Another “luggable” computer from the early days, this Kaypro II was an incredibly durable, albeit heavy system. The chassis and keyboard were made of steel, and though the two latched together to form a single piece, we dare anyone to carry it for a significant length of time. The display on the Kaypro is slightly larger than that of the Osborne I, but it also required a boot disk and wall socket to prove useful. Rumor has it that the producers of the film 2010 communicated work back and forth between the US and India during filming using this system and a modem.
