3.5" 1.44MB Floppy Drive Backpack with Parallel Port Cable

All is OK except, unit comes with only 3.5" floppy for installation. Note inside says contact company for 5.25 setup disk. Given they are basically out of business, not possible to get 5.25" floppy and therefore not possible to install on the machine for which I purchased given it does not have a 3.5" floppy drive.
