It's my understanding, that based on the distribution agreement, anything from the first system/finder release until System 7.0.1 is fair game to post, anything beyond that is a no-no, unless it was posed by Apple for free on their FTP server, then it's OK.

Also, 800k is Double Density, not low density. Low Density is 400k disks.

The hierarchy is low density, double density, high density.
