I was checking through some boxes and found these DEC 8" floppy disks
dated April 1980. They have gotten separated from something here and I
have no idea what at this point. Anyone know what these things are?
There are several other boxes of disks but these were the only thing I
saw that might give a clue as to what machine they run on.
