Atari Falcon 030 Microbox

Atari created a number of prototypes of the Falcon040 (based on the more capable fully pipelined, integrated-FPU, Motorola 68040, and using a "microbox" case), but canceled it.  The Microbox case resembled the later Sony PlayStation 2, right down to the ability to run it vertically or horizontally.  Sony purchased the case design from Atari; it's even referenced in the PS2 patent applications.
