The cassette player works, its a Technics RS-TR575. I cleaned it and used the power cord from PlayStation to hook it up to the power outlet and used the PlayStation Red/White/Yellow cable to hook it up to TV as speakers.
I suppose you're going to use it to play those "rare and valuable" vintage Village People tapes you bought from the guy on the streetcorner. Have a heart and hide your grandmother's hearing aid, first.
