Like its 2600 cousin, the Atari 5200 version of RS Basketball never made it into production. Why Atari couldn't get either version out the door before the crash hit is unknown, but it appears that they tried at least two different versions for the 5200 before pulling the plug. While the later version resembles the aborted 2600 version, the earlier prototype seems to share more in common with the Atari 400/800 version programmed by Alan Miller. Atari may have been attempting to do a slight enhancement to the early 8-bit version before deciding that it was ultimately too dated (the 400/800 version was done in 1979 after all).
