I have 9 pictures of the controller box but I don't know how to list them on here. It appears that it is just a transformer, a breidge rectifier, a large circuit board, an input from computer (from propriatary PC board), machine outputs (one for lathe, one for mill, one for spindle & one for robot) & a bunch of external fuse holders. If someone can give me an e-mail address to send them to, I'll e-mail the pictures. The pictures are all about 2mb each. I think considering I paid around $350 for this box, i'd be better off selling it to someone who has the PC card but a dead controller & just purchase the GEKO system. There's a guy listing them (Geko) on e-bay that has the whole 9 yards in one package for around $400. I tried to build a new PC to run this thing. I got it all togeather & can't get it to work. With as much as I hate computers, I don't know why I started into a computer centric project.
