I just bought a used cincinnati vmc equipped with A2100. Presently I am looking for a DNC cable details, as I want to run this machine on DNC mode. I am facing following problems too:

-- As this machine set for INCH units, I want to switch machine cordinates INCH to mm. Some body send me details for the same.
-- Machine floppy drive is not working?
-- Is it possible to add a hard disk or zip drive to increase space?
-- How do I interface this machine on network/ lan?
-- DNC cable details?
-- Installation and maintenace manuals?
-- etc.
As I am not familier with this control (Acramatic 2100), kindly help me please.
