This is a Pioneer 8-track deck. I believe it's an outdated 8-track deck from the late Showa 40s (around the 1970s) that my father replaced with a cassette deck. It comes with a mona adapter that allowed you to listen to cassettes back then. It was just removed, so I don't think it's broken, but it probably won't work. - Brand: Pioneer - Model: 8 Track Car Stereo - Accessories: mona cassette adapter - Connection Terminals: See images - Design: Showa retro car specification
