Quite the device! That really is about as good of a film to video image as you could get at the time without a telecine tech and their racks of gear.
Here is a link to the Normende super 8 unit:

there used to be an article online where you could see one of these opened up, but that seems to be long gone. Somewhere, I have some boxed super 8 cartridges that were to be used with these machines. The takeup reel was in the machine, and when you were done, the film would snake back up into the cartridge.
edit: I just remembered the Kodak's model#: VP-1 and VP-X. So between the Sylvania, Kodak and Normende, those were the flying spot film scanners available to the consumer during this period. Amazing that there were this many.
