At last, I've found them! They date back to early 2010 to late 2011.
go to https://github.com/windowsmas/Scratch-Experimental-Viewer which has them all listed there!
They are SWFs so you should be able to run them. Screenshot:

Het zijn SWF's, dus je zou ze moeten kunnen uitvoeren. Schermafbeelding:

Nice work!!

good, but is it possible to use it in production?

Does anyone have alphas from v121 to v132, v37 to v44, v28, v31 to v35, v139, v19, v24 to v27, v44 to v111, or a version of the early swfs with an editor, if any of those exist?
Anyway, I found a lot of other swfs from an archive that I can't link here because it's on an external website (a lot of them were from a deleted repository), so I'm working on uploading them, as well as some old projects/starter projects

Just made a commit and pull request (my username is artech-dvd).

What do you mean? I don't think I could find one after the latest beta version.

Thanks! I've updated it to show the other 2 early / testing versions. I hope more people pull request ../ contribute to this project.

Update on this project
I have come close to finding a .swf from 2012, but before the beta was released. I have found these while backwards engineering the archived website in inspect element to find a website for the download. However, while launching a found SWF, I wasn't able to use it, as it would display a grey screen and crash on click. Hopefully I will be able to find a working version soon, and I'll share the commit on GitHub.

Update over dit project
Ik heb bijna een .swf uit 2012 gevonden, maar voordat de bèta werd uitgebracht. Ik heb deze gevonden tijdens het terugontwikkelen van de gearchiveerde website in het inspecteerelement om een website voor de download te vinden. Bij het starten van een gevonden SWF kon ik het echter niet gebruiken, omdat het een grijs scherm zou weergeven en zou crashen bij klikken. Hopelijk kan ik snel een werkende versie vinden en deel ik de commit op GitHub.

I mean, the beta was released in 2013.
Some of those do that, I have some final release ones that crash when you load them. And can you link the archived site you found it in?

Here. You have to hack the source code of the site, it's not too difficult.

There are various late 2012 builds yet to be discovered. I am currently researching them..

Er zijn verschillende builds van eind 2012 die nog ontdekt moeten worden. Ik ben ze momenteel aan het onderzoeken..

Gd can’t be shared - that’s the thing. That’s where it was. I’m uploading them to github.

Link? also what GD? Godot?

Guys, we have some news! Scratch 2.0 v44 has been found, and it is pretty weird! Here's a look:

I updated the GitHub.

Yeah I've seen that one, someone's posted about it on Scratch.

There was a GD with archives (a lot from a deleted repository).
And here:
https://github.com/medlans/2.0-Archives
Some of these do the grey crashing thing.
