Hello and thanks in advance. Just took possession of two, Mori SH-403’s. Both have the MSG-501 control. The control says I have 130,000 bytes free space, but I cannot load a core roughing program of 110,000 bytes. On our NL’s, I have used DNC Tape mode to run a large program off the memory card. I did try the same thing on the SH but no luck. Does anyone have any ideas that may help. Once again, thank you very much.
