I just bought a Series 1 CNC machine and I am wondering how to ID which model I have (BOSS 3, 4, 5, etc). It has a non-rigid ram 2HP head with a pneumatic speed control, pneumatic brake, coolant pump, lube system, round heatsinks on motors, distance meters on screws, reel to reel tape drive, control panel (green, white, orange with keypad in lower right corner), etc. There doesn't seem to be anything which says BOSS on it. I can get some PCB part numbers if that helps.

Is there a way I can plug this thing in and see if it works? I have a 2HP VFD that I can remove from my other mill to power up the spindle. Are there other 3-phase components inside or are the rest of the electronics 120V? Does anyone know where I can get a schematic for the controls? Can this thing be controlled from a PC which drives the original drivers and motors? What kind of motors does this thing have (6 wire, 8 wire)?

Thanks for any help.
