I BOUGHT A PACHISLO! - need help!

[wrkey]

Ok, I found this machine on Craig's list for $35. (first photo) As you can see from the photos it lights up. It takes quarters and pays quarters when you win. Did I get a good deal or this machine only worth $35?

He didn't have the key for it. I can stick my hand inside the hole in the back and can slide what appears to be the sliding piece on the lock, but it won't open. (second photo is of what I can see in the hole in the back) Can someone tell me how to open it?

I've seen a video on U-Tube showing a 'big game' fever round on it. I also found a link in a PachiTalk thread which pointed to a 'research' entry for a Pegasus, although I don't know if it's the same one. That link was on an old thread and dead any way.

Any know the maker? Do we have a research entry for it?

HELP!

Thanks in advance!
