Bridgeport R2E3

I have tracked down this mill (vintage 1987) and am thinking of riping
out the electronics (9500 baud) and running it on a PC with Mach2 with
a breakout board and three servo drivers (if I can't link to the
existing 24 vdc motor controllers) Mill has a manual knee and 3 CNC
axes with the quill.
The Biridgeport iron looks OK, variable drive is quiet. I would like to
icorporate the existing CNC controls into the Mach2 keygrabber, etc, if
feasible.
Has anyone gone this route on a Bridgeport?

Thanks,

Harley
