The schematics are not on the net. I looked.
I have the manual, but my computer is wigging out on me. Also I am having problems loading my scanner drivers.
Once I get that squared away, I will be happy to scan the info you need.
In the mean time, you could search ebay. Currently the manual isn't available, but thats where I got mine. I did see it for sale on some arcade websites, but I don't remember what they are. Sorry I can't help more right now.
