There was a net with different coinbase hash in 2007, and a concept of proof source with just the basics, 3 cpp files or so... almost sure it was not a Windows app by then... afaik all versions ever in the wild where at least able to mine and connect to to other clients. The coins before 03.01 where all (testcoins) minted over that early conbase

So it could be that I mined with the Bitcoin 0.1 preview release from November 16 2008 or an older version on that 2007 coinbase hash?
Curious if anyone has additional info on that:

This is consistent with my recalling, also the client looked exactly like bitcoin core.
