Excellent working condition. It runs on 220v.

In great condition, all push buttons cleaned.

Has 16 cartridges installed. (See last picture for the sounds)

1) Cartridges can be selected without unplugging and replacing EPROMs

2) Both the internal sounds and the cartridge can be swapped out, so all 15 sounds can be changed, not just the top 7. There are two "slots" - internal and cartridge. Any of the 16 "cartridges" can be placed in either slot.
