Hi, we have 4 Nitsuko dx2na systems. They all have system software diskettes version 4.00.11.

Today I tried to make sure we had backups using command 0001. Only 2 had the backup system disk in the cabinets.

I can't read the diskettes. From another post I found on this forum, someone suggested they might be Intel RMX formatted. But finding a reader for that has proven futile.

So, I'd like to know if all system data is on the disk, so if I boot up using the backup diskettes and everything comes up correctly, does that mean I have a good backup?

Second, any way to make a new system software backup diskette for the 2 cabinets missing theirs?
