My VMC is a Fanuc control, My lathe , a HIT-18S is a Siemens 840C. Does take some getting used to, canned cycles are radically different. The Siemens is DOS based with a standard hard drive and lots of memory compared to the Fanuc. My biggest gripe is the Siemens only displays machine distance, absolute and relative are nowhere to be found, so the numbers on the display are for all purposes meaningless. My Hyundai is also a 1995 vintage.
