How to replace Anilam controls with PC?

Howdy,
I have recently bought a manual Bridgeport mill which
has been converted to ball screws and servo motors
using Anilam Crusader II controls. It has 3 axis control
with SEM servo motors (perm. magnet DC) on axis X, Y, and Z. The
Anilam system is not working except for DRO functions
so I am wondering, would it be possible to control
this machine using a PC and inexpensive software and could I
still retain the existing SEM motors? What would I
need in the way of driver boards for the servo motors (they are
missing)? The motors are SEM brand, MT30R4 and MT30E4, 135 and 75
volts respectively. I probably should be asking other questions but
I am pretty new to CNC control. Maybe someone can help me decide what
is the best way to get this beast up and running. Thanks in advance.
