SZ
Not positive about the SZ series. The only advice that I feel confident in throwing out there, is make sure that this series is .dxf compatible. The HA series was the first of the H-generation that was. We had a H machine and still had the proprietary double density non-IBM compatible programming. In today's times... it's a pain in the bum.
There's another fellow in this forum that has a CX(?) machine that he's going through this exact same type of headache with the programming compatibility issues.
Good luck!
