Need info on unidentified Sankyo machine.

[alverdine]

I recently purchased my first pachinko. It is a Sankyo in a Stellar case. I would really appreciate any information you could give me about this machine. It seems that there are settings that can be changed, but I don't know how to tell what they are. Also, the machine works, but there are some cut wires in back. They are yellow and visible in the attached pictures. I would love to know what these are for. A wiring diagram would be awesome if anyone has it. There are balIs stuck in the machine and I can't tell where they are supposed to come out. I am willing to disassemble the whole thing for ball removal and general cleaning. Is there anything I should know before taking the machine apart? I could not find this machine on the forum or the Sankyo site. Check out the pictures and let me know what you think. Thanks.
