I'm getting doubles of every board along with it except the main board of course. He had a parts machine he stripped before this one. Comes with extra motors, pumps, etc. Not a bad deal. It's a fanuc ot-ot-b control. Built in 1992.
I believe the spindle is at least 7.5hp and might be a 10hp. I see conflicting info online and forgot to confirm when I went to see it. So I can either fix the main board, need to confirm for sure, and run it with the old control or upgrade.
