Very interesting. I may work on doing this. I saw someone posted about a pause when the tape changed sides. Couldn't you just remove the actual tape from a cassette so it just plays forever? It wouldn't try to change sides if it never runs to the end would it? You just want to fool it into thinking it's playing the cassette. Might tinker with that if I can find one of these at the junkyard. Thanks for the link BackinBlack
