Retweake the interface between floppy and floppy drive. Now writes/reads 1 word in 3 cycles (real speed should be 3.2578). Busy times keep being the same, but this allow bad use of the floppy drive, editing the values before are writen/read buy the drive,
Fixed that the disk is ejected is teh floppy drive is deleted. Fixed that datafile not being created, and bad check of file existence.
