Thanks. Brain Baffler also has MM95 on it. I guess they used that name as well as MM78LA, or maybe MM95 is a later, similar chip.
B6100 is Football and B6101 is Baseball, so I bet Lesser programmed Gravity, too.
Battlestar Galactica is B6001, and I bet Auto Race is B6000. I'm not sure if Football 2 has a Rockwell chip. I know Basketball, Armor Battle and Sub Chase don't have Rockwell chips, and neither do the Funtronics games.
