I had my Z axis start going haywire. Swapped the A axis card with the Z and the problem went away. The card that was in the Z slot looks to be an original 1991. It is caked with, for lack of a better term, grime. I'd like to clean it up and try it again to see if that is the problem, but it would need to be soaked thourghly to get this stuff off. Any thoughts or suggestions?

Any service centers out there that does this kind of thing?

Thanks,
Don
