I just recently picked up a Fairchild 900 Series Standard 8mm camera for relatively cheap secondhand. I couldn't find a sub-thread specifically for double 8mm for I figured I'd post it here. It's a single-system Sound camera from 1967 (I think?) for the double 8mm format. It came with an external magazine for up to a 200ft size film role of double 8mm. The optics appear in fine order but I cant seem to get power to the camera. It's supposed to run off of a rechargeable battery in the handgrip. The wallmount and camera uses a 5 prong Din cable to connect the battery to the camera, and to charge the battery from the wall. Does anyone have any recommendations on how to go about looking into this problem? I know it's a bit of a rare camera, but any help would be appreciated. I'll include pictures of it below. I did manage to get the camera manual with it.
