I’ve been concentrating on getting the game up and running before doing anything else to the game. So far I’ve managed to get the game about 75% working… and WITHOUT the aid of a manual!! Speaking of which I managed to track one down, should have it some time next week. 

Last weekend I spent some time removing everything from the bottom board (one section at a time) and cleaning the 30 odd years of crap off the bottom board, using Nifti, and old toothbrush and rags. This is a step i've NEVER done in the past.. seems i've been looking too many of Nino's resto threads  I didn’t get a pic of what it looked like before, believe me it was filthy. Notice the screened on markings for each relay/switch etc… these markings could hardly be seen. 

And today while taking a break from repairing other peoples stuff, I removed one of the stepper unit discs from the bottom board so I could scan it to duplicate it. The second pic shows the stepper unit in question, after I took a pic of the wiring to the disc pcb, I unsoldered and removed the disc. Next I took it into my PC and scanned the disc at 300dpi, and spent a couple of hours editing and cleaning up the image, the 3rd pic shows a test printout on plain paper.

This will be printed onto “Press n Peel” film (a special type of transfer paper for making PCBs, available from Jaycar) on a laser printer, and ironed onto the copper board, (using an ordinary clothes iron) and then etched. I’ll describe the process in more detail (and post pics) when I get around to making the boards.. for those of you who are not familiar with making PCBs.
