Article from 2019 claims 2 nodes are running 0.8.1 I have no idea if this is still the case. There are a bunch of sites that will tell you what version the nodes are running. I know for sure nodes need to be updated to the 0.3.1 softfork to avoid the overflow issue.
I am currently downloading the blockchain with the latest version (v23.0).
Will then check which versions can validate the already downloaded blockchain.
I think that should check backwards compatibility, right?

But since it was a soft fork, wouldn't that mean the nodes before 0.3.1 would still sync? The rules got stricter, so the old nodes would still see these "new" blocks as valid.

Ah, thanks, that looks interesting!

It looks like there is a node running Satoshi:0.8.2.2. If you find out how far you can go back I would love to know!
Hey, I haven't forgotten about you yet. Will reply when I found out!
Okay, I am currently unaware how to verify the full blockchain.
Seems like Bitcoin Core only validates the last 6 blocks:
