Found this at a Malibu estate and likely belong to somebody that worked on the show Lassie. There were a ton of slides for the opening credit sequences and promotional tours of Lassie the dog. The unit has been wrapped in a plastic bag and there is a receipt from Kodak being serviced in 1988 stating that it is fully functional. When I plugged it in everything turned on, including the lights in the fans and the remote advance buttons worked fine
