A really helpful guy from the USA (Peter McDonald
http://www.zpinaddict.com/pballhtm/pinball.htm) was able to email me a PDF of the schematic for this machine. He has owned a shitload of pinballs (mostly EMs) and has quite a large stockpile of manuals & schematics if anyone is interested.
I invited him to join our little group, he should be quite an asset over here :)
