Hi
I have a Bridgeport GX-1000 machining center with Fanuc oi-mc control. I turn on the machine and the machine every time goes in System Monitor Main Menu Screen and an error blinks



ROM PARITY ERROR: NC BASIC

There are 2 files are still in RAM
SRAM1_0A
SRAM1_0B
So I think there is no memory loss and maybe only 1 file (NC Basic) is missing. How can I get this file and how to copy?

Please help me to solve this problem

Thanks
