I don't believe there was a .85 or .xx whatever version for the 128k Mac. I ran the original version of the OS and it simply said Macintosh Software under get info for System and Finder.

I doubt they ever made a version of Lisaworks that patched in the original unenhanced version of the Mac ROM like the ROM in a 128k or a 512k "FatMac".

In order to see the actual system version on the Guided Tour disk you have to use resedit and look at the resource code, where .85 and .97 are designated for the original MGT and System software. There is no question that Apple was using system versions internally during the development period. What I was asking was whether Apple really broke the Tour's compatibility with System .97 and only discovered it in the 11th hour.

As for the Lisa, MacWorks was introduced in April of 1984, LONG before the 128K ROM was introduced in the Mac Plus. As a result the Mac ROM code loaded into the Lisa RAM is most definitely the original 64K ROM of the Macintosh, 128K and 512K. Considering the Lisa was discontinued in 1985, it is doubtful Apple ever updated the ROM code in MacWorks, though Sun Remarketing certainly did. That is one of the reasons that MacWorks 3.0 cannot run much above System 3, just like the original 128K. Odds are, there are other mitigating reasons MacWorks cannot run the original MTG.
