Thanks for the replies. A little more searching turned up a "continuation" of the company - as "Servo Source" - spoke with the owner (apparently the original designer) - some parts are still available.
The original electronics are very much out-of-date - Z-80 based! The unit on Ebay is the mill and servos (Pittman) only - would need a driver assembly and software.
I'm waffling a bit because the unit looks as if it is well used and spindle and/or ball screw&nut repair would be expensive.
decisions, decisions
