It can support the legacy machines but the DOS EEPROMS are below the threshold. The 2.1 EEPROM should will work with the existing card, the L on card seems to mean a coms problem but i cant for the life of me find out what it is! Beer tokens it is, i am determined to make VR Work for me in the short term.. what the value of beer tokens these days lol!

Cant say i have heard of the Dynomotion's KMotionCNC, do they offer a hardware package?

If i have to go down the conversion route i can see me using a pneumatic button release on the drawbar until i figure out the magic of the ATC.
