Well, the computer does know if it is a DS or SS disk. On 8" disks,
its a hardware feature. Look at the index hole, and youll see that
the hole is shifted a few degrees between SS and DS disks. If your
feeling brave, you can use a hole punch to change it :-)

Try Inmac, or any of those mail order companys, they usually 
still sell 8" diskettes...
