Hi Dave, The servos and feedback are very similar to what Hardinge used on the smaller chuckers with Fanuc controls. That is, conventional DC brush servos with resolver feedback. Jon Elson has recently added resolver to quadrature converters to his product line, and Matt Shaver previously figured out how to put a tiny optical encoder into the Hardinge resolver/gear assembly.
As you said, few old machines of this age are still running original electronics and that is why I took advantage of the opportunity to grab spare cards, including all the CPU, memory, console interface, and resolver/servo interface ones. I also have a complete CRT/keyboard/console and a spare for the main DC spindle drive. There should be some servo amps, but I cannot find them at the moment. Also included is some tooling for the turrets, a few 16C collets, the 16C to 5C adapter, and other odds and ends. I was playing it safe guessing the age of the machine. The training manual that came with it says 1988, like 4 years really makes a difference. 8-) The machine is a model SB3-GN, s/n SB-252R. Sadly, it may get stripped for parts. I need the space and will never have the time to retrofit it.
