Hello John,
I've just read Gunner's reply and he might have hit on the problem here because when the first floppies came out they were 2DD and not 2HD. One of our Club members bought himself a very old but in excellent condition organ with a floppy drive and he couldn't even save his own settings so called me for help. Not knowing much (if anything at all) about organs I went over to his house just to see what his problem was and of course I discovered on reading the manual that it would only work with 2DD floppies and fortunately for him, I had one or two in my stockpile that I had used on earlier KN Keyboards. I gave them to him, he formatted them in his organ and hey presto! they worked. So like I said, maybe Gunner has hit on the reason for your problems.
However, if this isn't the case I think your son WILL be able to help for again, way back when I had my first PC it used the DOS system and although I am no expert - (but I know a man who is) and he could get my PC to do anything he liked and to this day, he still uses a DOS system simply because "the system is constant and doesn't keep changing involving more and more expense" his words not mine.
I hope you will keep us posted on this one as I am intrigued as to what the anwer is.
Good luck!
Audrey
