Alright, I know you are all saying, "urghgrhgh, another mediocre event build from this kid.", but this one is better than my adding machine. I basically used relays to put on a disk, and once the relay was fired up, it played the music assigned to the disk. Pics:

Choose the disk, and put it in the slot.

Close the cartridge, then hit the green button for play. To turn it off, twist the black dial at the top.

Listen to some funky tunes!
I am working on a more complex V2, and then for V3 I will make it have an FM radio along with the disk cartridge.
Here is the save, please do not steal it from me :P
