Realsports Baseball for Atari 8-bit computers?

[VideoGameCritic]

The latest Retro Gamer magazine had a spread on the Atari Realsports games, and mentioned that while Realsports Baseball for the 5200 is great, it says you might want to play the "8-bit adaptation" so you can avoid using the Atari 5200 controllers.

Has anyone ever heard of this? I'm not sure how it would work. The 5200 joystick had an analog quality that would be hard to emulate with a standard joystick. Also, how would you select your pitches without a keypad?

I'm not aware of RealSports Baseball for the 8 bit line.
