Is there anybody there with Bridgeport RS2E3 CNC Mill(Early 1980 models)

Please share me your experience about Retrofitting the servo motor
drivers with Geckos on the above subject. In the first place would
like to know whether they are compatible.

I'm new with cnc. The extent of my experience is having successfully
made and operated 18" x 24" x 6" Router, made of steel and driven by
2-amp, 3 axis from Camtronics. It is run by CncPro.

This is my first question and new to the group. Thanks.
