Thrift store find. I saw this Kodak Disk 4100 with a film cartridge still in it - although this is almost 40 years old in 2023, the motor still ran when I pressed the shutter button. The film was on a wheel of 15 shots that rotated. It had two 3v lithium batteries, which still held some charge even now. The batteries could be replaced by Kodak technicians, but the camera was discontinued in 1987, and Kodak officially stopped making the film at the end of 1999.  The batteries are CR123a, still readily available I used one like it in a waterproof case scuba diving. It didn't take good pictures due to the small size of the negative. Also film processors often didn't use the special equipment to make prints from it.
