Depends what you mean by "real-time display of position in Mach3"
If simply wanting a display in Mach of position then you could just hook up glass scales and input to Mach set up as Encoder inputs. If using the parallel port then there will be a limitation to the frequency and thus velocity, think 25KHz would be about Max if I recall correctly.
If wanting to have the axis position DROs constantly updated from encoder feedback then you would need a controller capable of doing that.
The CSMIO/IP-A does that but you would need analogue command servo drives (most Industrial AC/DC drives are ).
The Galil, DSPMC, Hicon I think can also update the DROs but not sure if they are "real time".
