Hey Brett, it has an OSP5000 control, apparently there is an intermittent problem with the control booting up. It's an older machine and control with a tape reader, mechanicals are in very nice shape with Fanuc servos. The Okuma guys seem to think the control is a good one and there is a device that takes place of the tape reader and accepts input from a pc. I'm interested if anybody has done a retro to Mach and how easy or difficult it is, if there ends up being a good reason to replace the control, Mach may be a good replacement.
