In conjunction with a 4 kByte EPRom, the PA 1205 enables title recognition, the programming of up to 19 titles, as well as the display of all operating states on a 4-digit LED display. After switching on the device, the support arm moves over the placed record. An optocoupler installed on the support arm detects entry groove, number of tracks, as well as exit groove, and stores their positions with the help of the microcomputer.
