About me

Industry Non-Profit
Location San Francisco, California
Introduction ABACUS is an informal group of current and former Atari users who meet once a month to discuss various computer-related topics, and to share information, tips, and rumors. Established in 1981 by former Antic and STart publisher James Capparell, ABACUS is the oldest continuously active Atari user group in the San Francisco Bay Area. ABACUS currently supports both Windows and Macintosh users, as well as collectors of older computer and video game systems and paraphenalia.
