Allen Bradley cnc control Model?

Hello everybody,

We just purchased a second hand 5 axis machine made by CMS in 1996,the cnc system is made by Allen Bradley but we are not able to find any possible information about this particular model of cnc controller.
Any Ideas about it or information? the machine was sold with a reported problem to this cnc control so we are looking for assistance in order to fix it before thinking about a retrofit.

Thanks so much in advance for any information!

L.G.
