I've written RX50 floppies on a Linux PC, after setting the format to the
correct setting (10 sectors per track is the main change). That was using
stock real RX50 floppy media; I wouldn't want to try low level formatting
floppies that way. The interleaving was handled in software (using my FLX
utility for manipulating RSTS file systems).
