I am looking at buying a mid/late-1990's DYNA EM3116 CNC Knee Mill, 3 Axis with Dyna 4M PC-III Control. Anyone have any knowledge or experience with these machines? What are the controls like for programming on these machines? I was kinda wondering about the overall construction of the servo system. The servo drive motors seem to be very small compared to most others. Comments please...

Thank you
