anyone with an early Option Board?

Many methods were used to write special format tracks on drives and then check for their presence in the field by installation software to be sure only diskettes with the devices are able to successfully run the software. I believe it used flux transition methods to record what was on the diskette tracks, as well as having some awareness of some software packages to be able to duplicate media. The copywrite program also referred to here was a software only program to do the same thing. If you wanted to back up your installation media these two programs covered most available packages during that time.
