I hope this is not inappropriate to post here, but I just started a new blog on arcade game history from the bronze and golden ages.
The blog is at:

Only three posts right now (more coming soon):
One is on some info I found on the early years of Cinematronics
One is on The Bishop of Battle
One is on an arcade game that might have used a microprocessor before Gun Fight (plus a lot of info on Gun Fight, Bally's first try at putting a microprocessor in a coin-op (before Gun Fight), and forgotten pioneer Jerry Lawson.

I am doing so in part to gauge interest in a book that I started writing about 15 years ago (subtitled, mildly tounge-in-cheek, "The definitive history of arcade video games, 1971-1984"), dropped, and an now contemplating finishing.
I want to see if there enough interest for me to do so and figured if people here weren't interested, no one would be.
