In 1980, we had a CPM computer that had 2 8" floppy drives.

I could load one disk that had a word processor. And it could load another
that had DBASE 2.

Of course when you loaded DBASE 2, the cursor was just a *, and every one
thought it was broke.

Joe,
Don't think there was ever a floppy disk larger than 8-inch. I never used
8-inch on a computer per se, but only on a dedicated "word processor."
