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). paul _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
