Same old story: Controls put in in 1983 are getting old refusing to function properly. The people that installed these controls have long since retired. There is no factory support either from the Machine maker, nor from the controls maker. Old software would need to be located and a long learning curve (dollars and time) would be experienced to get the system working.
