Questions on a Bridgeport X26 CNC mill

So I have a Bridgeport Explorer X26 at work and it has recently lost the ability to use the floppy drive (current controller runs on MSDOS) which makes it so I have to program at the machine. Obviously this can be a bear with long programs, and this is the only machine we have with a tool changer.

I was thinking about upgrading the thing to use a new motherboard and slap linuxcnc on the thing, but as far as hardware goes, I'm not exactly an expert. Anybody have any experience with upgrading one of these that can tell me what kind of hardware I would need (preferably just the boards, the servo motors and everything else seems to work ok) to get this thing upgraded to the point I can run LinuxCNC on it instead of the DX-32 stuff that is on it now?

Awesome, Did your machine have a z-axis and speed control on it? The way it looks on mine, the speed control is exactly like a standard bridgeport with an air motor to change the speed. Do you know if these boards work OK with this type of setup?
