What a fun little sequencer! I'm not good at programming it, but there are some really nice patterns that you can loop and then hit the drum buttons to pretend like you are doing something.
This thing was made in later 1980s, i think? I tested it out with a 9volt power supply and it works. Not sure if the midi stuff works, I don't have any cables.
What you get:
* Yamaha QY10
What you don't get
* Power supply or any cables.
