You should be able to do it if the servo amps are separate units that can
be separated from the rest of the Crusader control. Most servo amps
use a +/- 10 V signal to command the machine's velocity.
The encoders are usually quite simple to hook up. There are also
a bunch of limit and home switches that are fairly straightforward.
Finally, you need some hookup to the spindle control, the estop chain
and the servo amp enables.

There are 2 ways to go. 1 is Servo-to-Go, http://www.servotogo.com/
The other is the Parallel Port Axis Control at
http://pico-systems.com/PPMC.html which connects to your parallel
port, so it doesn't need a slot in the motherboard.

There will be a digital I/O board added to the PPAC product soon.
It integrates optoisolated digital inputs (limit switches, etc.) and
solid state relays (spindle control, servo amp power, etc.) right on
the board, so you don't need to add external Opto-22 module racks.

With the STG card, you need external Opto-22 racks for the output, and
more if you need opto-isolated inputs, too.
