This decreases the amount >of loose material floating around inside the disk. > In the Decemeber 1989 issue of IEEE Computer magazine, on page 90 (in the product reviews section) there is a little article on a device specifically designed to punch a little square hole in DS/DD floppies to make them into HD floppies. The device is called the "DoubleDisk Converter", and sells for $39.95 from Biological engineering at 2674 E. Main St. Ventura, CA 93003 . Their phone number is (805) 644-1797. Quoting from the article, quoting from the manufacturer "There's a greater variation between different manufacturers' specifications for high density disks than ther is between a manufacturer's double density and high density 3.5 inch disks". Draw your own conclusions, I'm sure I don't buy enough floppies to warant hasseling with it either way, let alone buying this item but, if you were a real floppy-ite it might warant some investigation. -jrg -- apple!jrg John R.
