These are Mac only so hopefully a Windows user will do likewise at some point...
The versions available are: 1.24, 1.26, 1.28, 1.32, 1.36, 1.40, 1.44 ,1.46, 1.50 and 1.52
They're all individually zipped up and located at: https://tinyurl.com/y9o379kj
The (current) Dropbox interface is not particualrly intuitive unfortunately so...
If you want to download ALL of the eight versions I've posted, then simply click on the 'Download' tab (top-right) and select 'Direct Download'.
All eight ZIP files when then be automatically zipped into one big ZIP file called 'Nord Stage 3 OS' which will then be downloaded.
However, if you just want a single version, first of all click on it.
You'll then see a page with just that version's app folder on view.
To get hold of the single ZIP file, again, just click on the 'Download' tab (top-right) and select 'Direct Download'.
That single ZIP file will then automatically be downloaded.
I'm still sticking to 1.36 as it works perfectly for my requirements though I believe 1.40 is supposed to be a good'un too judging by what various posts have to say
Admittedly, I believe the organ sounds are supposed to have improved a bit since 1.36 but as I use a GSi Gemini for all my organic needs...
And there's definitely no voice-stealing in the synth section for that version!
