Editable logic password machine

You need the newest snapshot! Get it here.

This is just something i'd like to share, its expandable to 7 buttons (I only used 3). Fully editable password codes and quite compact. If you are willing to make one that is with 7 buttons then go ahead. I've included this as a McEdit schematic so you can import it on you're serer, adventure map, world etc. You need the newest snapshot for it to function, you can get it here. You can remove the edit feature if working on a adventure map so the player can't edit it. Hope you enjoy this little machine!

Additional Notes

Need the newest snapshot, 13w01a or newer!
