Looking for advice on converting driver on Boxford CNC Router to Mach3/4

[yankyg]

After reading loads here, I'm looking for some solid advice on converting a Boxford A3 HSRi2 router to work on Mach 3.
Would be looking at the MX4660 driver, and removing the old motherboard and driver. (see history below)
I can't get a schematic, but think I need to test each cable to find out what it is, match it to the new driver, and set it up.
Is it that simple?

History:
Machine currently works okay, but I don't like the Boxford software which is very basic, and needs hard resetting frequently. I For example, if accidently set on machine to manual mode, the CNC does not communicate with PC, so if you attempt to run a job, it gives an error message "machine not responding" and requires a hard reset.

I've converted one of these to mach3 for a customer. Pretty much everything needs to be removed except for the Spindle board.
Personally, I wouldn't use MX4660 as there are cheaper better options if you use individual components.
I'd also suggest you go with an external motion controller rather than use the parallel port as it's much more reliable and when used with good Digital drives turns this machine into monster compared to using Boxford setup.

The setup I used was this.
Cslabs IP-M motion controller. This is high quality controller that provides 24Vdc I/O with spindle speed controller. It removes the need for breakout board which is source of trouble on many machines,

Leadshine EM503 Digital drives
44Vdc toroidal PSU

Unfortunatly I didn't take any pictures of this conversion but it's very similair to this one done on Denford Router.

And what would you charge to do the change? Maybe it will work out cheaper for me considering the time it will take.
