Thanks for the comprehensive explanation.

Actually I have even three in my office machine. I have one of those
Teac double disk drives, with a 5,25" floppy and 3,5" diskette drive,
intended to be A: and B:.

I did however rewire the pin block, and added a switch, so that I can,
switch either of them to be an A: drive.

In addition I have a 3,5" drive as B:.

I'll have to save this message for future use.
I have nothing against learning a new operating system, but the only
thing I hated and didn't like about *nix was the case sensitivity.

So far I have recirculated the old Windows and OS/2 installation
diskettes, and reformatted them. There are plenty of them.

I know that a safer media is USB sticks, as long as you don't abuse them
by writing too many times on them.

Yes I know, that's why I bought a machine with Win 7, and upgraded it to
Win10.


Have a good morning,

Holger
