Uhm, I do read English. My remark aimed at the writing mistake that tells me about the OP’s care.
Dear Stefano, what you have is a film camera. A camcorder doesn’t have film inside. Film is something chemical. Sorry for appearing schoolmasterly but the question can make us film-dwelling people chuckle. To be quite frank: Kodachrome was the stock of the time.
Kodachrome isn’t made anymore.
You can use any Super-8 film with your apparatus. Keep in mind that they are 30+ years old and might be in need of overhaul if not replacement. There’s a fresh Super-8 camera on the market, the Logmar, and there are better projectors around.
Like with most Compact Cassette recorders from the seventies: throw-away products, consumer goods industry
