Buying a 1985 Mazda RX-7, need help with it

Where would be some great articles of sorts to read up about the RX-7's? This is my first ever project car, and it seems I bit off something large when I got something with a rotary engine, since I keep hearing about it, but know nothing about it. If anyone can help me find articles to fixing the car itself, and maybe some describing a rotary engine, that would be excellent. As I said, it's my first car, and it could be a ELIF sort of scenario, as I grew up without any father figures around to teach me much.
