I've just seen your posts over on the Denford forum. I wonder if Denford still have the file for programming the EEPROM, and if they'd be willing to make it public. I'm sure I've read somewhere they no longer have the ability to program them themselves, but I'm sure somebody with a suitable programmer could be found, although new chips may be a problem...

KMotionCNC requires a KFlop, which is Dynomotion's motion controller. I'd like to say retrofitting a Denford was straight forward, but it gets quite involved depending on what you want to achieve.
Once I get mine up and running, you'd be more than welcome to visit.
