What type of film can be used in a Polaroid 80 Land camera?

You need Polaroid SX-70 film. There is a group of people doing something called The Impossible Project (google that and you'll get to their website) which is recreating Polaroid instant film. This is apparently harder than you think--the company that made the dye Polaroid used, which is very unique stuff, won't make any more nor will they tell you how to do it, so the Impossible people are creating one of their own.
