This is what I always wondered about the 8-bit trackball (CX-80):

CX-22 - original model (white ball, round fire buttons, T/J switch on bottom)
CX-80 - redesigned model ("XL" style, black ball, triangular fire buttons, T/J switch on back).
Note that there are 2 different versions of the CX-80 model. The first version is compatible with the CX-22; the 2nd is compatible with the Atari ST mouse (some jumpers were added to the board inside). The only way to tell which version you have is to either try it, or open it up and look for the jumpers.
Ironically, Atari only made one game that takes advantage of the "trak-ball" mode, 8-bit Missile Command. No 2600 games (by any company) use it. However, last year Thomas Jentzsch made 2 modified versions of Missile Command that use it (for either model).
unquote.
So sadly, only Missile Command seems to really support the trackball mode on the 8-bit. Now since the 5200 basicaly IS an 8-bit, and a number of 5200 only games have been ported to the 8-bit, would f.i. Centipede support it ?
Reminds me that I gotta dig up that 800 (NOT XL) PAL version (RARE !) that I bought some years ago.
Gotta play some Miner and Bounty Bob again
