The August 5 gathering of Boston Post Mortem, a casual, beerful get-together of professional (and otherwise) video game developers, will feature a presentation by Ralph Baer, the man often credited as the inventor of the home game console. He'll have a "brown box" prototype of the first commercial game console, the Odyssey, on hand as well.
The presentation will be at the Post Mortem's usual venue, the Skellig pub in Waltham, MA. Consult the link for full details. I plan to be there; say hi if you spot me.
