Due to a scheduling conflict, the December 2009 ABACUS originally planned for Saturday, December 5th has been postponed until Sunday, December 6th. We regret any inconvenience this may cause.
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.
