Retro fitting an old Dahlgren engraver.

I have an early Dahlgren CNC engraver and want to retro fit it to run programmes like Mach 3 and V Carve.The machine is very substantial in build quality and it seems such a shame not to use it.Is such a venture possible? and,if so,what would be recommendations for this retro fit.Although I have programmed CNC`s in the past and run them,industrially,what I know about electronics I could write on the back of a stamp in big letters.I eagerly await your comments.
