It's a system 1, and I'd say it's not one of the better ones. The sound is awful on that machine...but you can retro-fit a chime box in it. The vari-target is cool, but overall it plays just like a EM. I would say the gameplay is so-so, it has the basics, pops, drops, roll overs, and the vari-target. Just be aware that the orginal CPU and soundboard have parts that are no longer available. And for the record, not all System 1's are stinkers- Sinbad, Joker Poker, and Genie, are great games in my opinion.
