Hi ya'll, So I just ordered some of the BRAND NEW SX-70 film from the *possible project!! However, that has nothing at all to do with my post.... Serendipitously, on this same day, I went to yee ole' antique mall and found some unopened 600 P-film for $3. Awesome. However, I put it in my Sun Autofocus 660, I remove the darkslide, it powers up the flash, indeed it flashes, and the motor starts whirring, but no picture ever makes its way out. The counter counts down, but still nothing. I tried a couple times, and even took it out and put it back in (yes, sacrificing at LEAST the first picture). I admit I haven't loaded or shot with a polaroid for well over a decade, but I'm pretty certain I did everything correctly. (though the complete lack of instructions on the film package is maddening). So, what's wrong here? Is my camera busted? Am I missing something? Any suggestions would be appreciated. Thanks, Chris H.
