[Emc-users] Hurco KM3 to retrofit - now what do I need?

Well - I've gone and done it, I bought another Hurco CNC mill. My existing machine was a 1990 KM3P with the MAX32 upgrade and the whole 9 yards of software upgrade options... Which is fantastic - if it would only boot. This machine is kinda unique with many special gotcha's if you were trying
