1970 Motorola Teleplayer Model CR100GW

The EVR cartridge held up to 50 minutes of black & white 8.75mm sprocket-less film with two magnetic stripes providing stereo sound. The original cartridge contained two tracks A and B, each with 25 minutes of b&w programming. The color format provided only 25 minutes of programming since Track B held the chroma information. CBS Chief Scientist Peter Goldmark invented the format.
