OK, sounds like an old BOSS servo control. Does it even have a CRT,
or just LED digits?

Anyway, you may be able to salvage the power supply and servo amps,
which will save a lot of money and hassle! If you want to keep it as
a servo machine (does it have handwheels?) with direct readout of
position, then you can only use a couple of CNC programs, as most
are not closed loop. EMC is one of those, that's what I use.
You need a servo control interface. Servo-to-Go is one, I also make
one.
