I couldn't tell how big this machine is. It most likely has DC servo
motors, but may have resolvers instead of shaft encoders. These will
require a converter/interpolator, or need to be changed to encoders.
Servo amps may need to be changed. The CNC control has got to
be one of the oldest I've seen, must be mid 60's.

Note, this is a 2-axis CNC. The quill feed is air operated.
