The very first hardware based polygon system, origonally called the 'Polygonizer' system, it later became known as System 21.
This system comprises 4 PCB's that slot into a backplane, which are housed in a metal crate.
At the moment it seems like there are 3 revisions of the hardware, Winning Run was a mass produced prototype for the System, the early games used 5 x TMS320C20 and later moved to 4 x TMS320C25...
Uses the Namco NB1 sprite system for the 2D graphics.
