Hoping MacTec chimes in but....
Does anyone know how the BMDC board communicates with the servo amplifiers? Is it a proprietary protocol or is it standard analog +/-10V?
I'm talking about the mid 90's machines with DC Brush Servos

Just the normal standard +/-10v well all the TC1 Etc do but they have AC servos, I don't think the BMDC boards are very different from the TC22 to the TC1 Etc, may have some different onboard software changes, some of the machine parameters are different that's about it

Thanks. It would be great if they did use standard analog input, but I vaguely remember reading somewhere that the DC Brush drives for the Today Cur 22/30 were proprietary to Bridgeport?
Are there schematics/pin outs out there in the wild for them to verify?

A lot of Bridgeport parts are propriety to them, just as any other manufacture of machines of all kinds, those old drive are for sure, as there was not much choice back when they where built, most manufacturers made designed and manufactured there own parts, just as some still do, Haas being a great example of that
