It's been nearly 7 years since I did anything serious with Bitcoin, I've forgotten nearly everything since then. I fired up Bitcoin Core and pointed it at an old wallet.dat I had laying around. There's a transaction I don't understand. Can someone help me understand it?

Does this mean that back in 2010 I was mining (sounds right) and generated some blocks that didn't get accepted by the network? Since the blockchain has moved on it's no way for me to get any btc out of it?
No idea, I think you might be better of trying this section of the forum:
