Dear EDM users,

I have an old Charmilles Robofil 400 machine. I have a problem. The machine was not used for a long time, and does not start. I try to reinstall the system from disk but don't work.
I rehearsed these steps:

1. I switch on to main power
2. pushed continuously the button load floppy try to load
but I come this error message: Loading # CKS error format

I try to change floppy to same type but don't work nothing, like this can be excluded the mistake of the floppy.
What may be the problem, hardware, eprom, floppy cable?

Please help,

Thanks your attention.

Best Regards,
