What's the deal with LOS 3.0 / 3.1 / 7/7?

<< < (2/2)

Alright! Here's a clue to what I think is going on. That "Good things to know about Lisa" document has proven pretty useful here.

In reference to copy protection, that document says:
"Protected Lisa software distributed by Apple includes all Lisa tools, except for LisaWrite and LisaProject 3.1"

In reference to upgrading a hard disk from LOS 3.0 to 3.1, it says:
"Replace the LisaWrite and LisaProject tools and stationary pads on the hard disk with the updated versions."

In reference to migrating documents from Lisa -> Mac, it says:
"There is only one version of the Migration software and it is intended to be used with Office System 7/7 Version 3.1".

Looking at the versions floating around online and going through their disk images with a hex editor, I've found that only LisaProject and LisaWrite Disk 1/2 reference being version 3.1. All of this makes me inclined to believe that LisaProject and LisaWrite (by updating one disk of the two) were the only 2 tools updated from 3.0 to 3.1, perhaps to support the Lisa -> Macintosh migration that only ran in 3.1, but also with the side effect of removing copy protection for those two specific tools.
