Are you interested to discover what is different about 7.1.1 (7 Pro), or is it your hope that there will be something different in it? It cost USD150, was the same as 7.1 but with the addition of PowerTalk, AppleTalk and QuickTime, and it was aimed at business users.
PowerTalk was a grouse idea for a transparent networking connection to everything, everywhere. Trouble was that no-one else ever caught up with it. By the time of 7.5, PT was three 1.4MB floppies-full, which 68K machines didn't have spare RAM enough to handle. 7.1 is on the July '93 Developer CD. System 7 Pro is on the Jan. '94 Developer CD. There are three disk images for the System, two for PowerTalk, and one each for AppleScript Setup, BYI, Disk Tools, Fonts, Printing, QT and Tidbits, making 12 images (or disks) in all.
