There's a free Atari party in just over a weeks time in Sunnyvale, CA in the SF Bay Area.
Lots of machines and games to play on spanning Atari's history. All free to play. Al Acorn of Pong fame will be giving a talk too.
I'll be there with an Atari 600XL and a BBC Micro both setup for a bunch of Atari classics so swing by and say Hi.
