Can't figure out why, but Edmonds was not the place I thought you would go to get one of the rarest Atari 2600 cart. But this is going to change, this guy is selling on CL a complete copy of the Music Machine, along with the record that goes with it.
This game was only sold in religious bookstores. It’s based on a line of The Music Machine products that also included LP’s sold by Sparrow. Cart only go for $200+ on eBay (well some ask for more, but they sell for $200+).
