<-bug food Does anyone out there know of a good way to copy protect programs on floppy disks? The method must work on a variety of MS-DOS running machines including the NEC-APC (8 inch disks) and the DEC Rainbow (5 1/4 inch disks, single sided, quad density). It must also be usable in mass production and we would like to be able to allow the legitimate users to make backup copies. Any pointers to such a method will be greatly appreciated. p.s. Any method we use *MUST* be unbreakable :-) -- David Shanks ..!tektronix!ogcvax!metheus!cdi!shanks Teneron Corp.
