[Simh] VAX 8200

I think  you need 1.2M floppy drives for this. I seem to remember THAT 360k drives don't work for reading RX50s.

PCs can read RX50s if you have a 5.25 inch drive.  DOS, or old enough versions of Windows that you can issue BIOS calls work.  On Linux, you can set the floppy parameters to 80 tracks, 10 sectors, single sided, and then standard utilities like dd will work.  If you have a floppy image you may need to process the interleaving to get to an image other file system utilities will handle.

My FLX utility (on my Subversion server or in simhtools) can do this.  I have a newer version in Python that can be used as a library, and includes an interleave/de-interleave tool.
