I once encountered a floppy diskette that was part of the Microsoft Word 6.0 installation set. This was apparently a special edition, because it was on a 360K floppy diskette. I believe it was disk x of 100 something.
I still have Windows 98 on 5-1/4" floppies, because Microsoft offered to send it to you for free if you bought the edition distributed on 3-1/2" floppies. I have two sets because for some reason they shipped me two copies when I requested them.
The 5-1/4" distribution of Windows 95 is unique in that it's the only distribution of Windows 95 that doesn't require a CD key or fingerprint the diskette when you install it. For years I had a copy of that on CD that was the contents of all the diskettes copied into a single directory and burned to CD. It's the most primitive and first release of Windows 95, back when Microsoft was competing with CompuServ and AOL to be the 'Online Service', hence from before 'the Internet' had been discovered by Microsoft. It's really 'clean' and small with no Internet Anything installed. And as the first ever version of Windows 95 it has EVERY bug of the initial release (obviously)
