I finally had a chance to poke around inside the scanned documentation you uploaded. Thanks so much! I haven't got past (double)-checking the information about what is on each disk, but so far what I have checked is accurate and very informative.
@snuci: Would you mind if I were to make a page on Macintosh Garden and upload both the disks and the documentation? I don't think any of these disks are on the Garden, and someone might have copies of the missing disks to contribute. But if you'd rather not, I won't do it. If you don't mind me uploading, I can also link to your archive (vintagecomputer.ca) or not, as you prefer.
There should have been at least one set of supplement disks before the ones you have - I believe it was dated 9/84 (although the documentation refers to updates being sent out scattered over time, so for all I know there was more than one version). References I have seen in contemporary magazines speak of Software Supplement versions issued in Sept 84, Feb 85 and May 85.
Thanks again for sharing these! The oldest stuff is incredibly difficult to find.
