Title: Which of the first 36,000 blocks have spent generation outputs?

Is this information compiled somewhere? It's a pain to manually scan the blockchain, block by block.

Block #170

That's the expenditure of the reward from block 9, and the first transaction involving two bitcoin addresses.
Block 9 was spent. That, and block 78, are the only two I already know about. :P
The reward from block 170 (https://blockchain.info/tx/b1fea52486ce0c62bb442b530a3f0132b826c74e473d1f2c220bfa78111c5082) is still unspent, however.

Manually parsed first 50 blocks.
Only block 9 so far.

Edit. Manually parsed up to block 80.
Blocks 9 and 78.
No surprise to me yet, but I'll keep going to 100.

Edit. Manually parsed up to block 100.
Nothing new.

79 to 100 appear to have been mined by the same person. Satoshi?

Edit. I'm going to use the idea that the incrementing extraNonce is the same computer and skip to where it resets.
There's another ramp starting at block 127. This is where the eN reset.
At block 163 stuff gets weird.
I'll start parsing from there.

Edit. Manually parsed up to block 200.
Zero new spent coinbases.
There are some transactions starting at 170 but 100% of the circulating bitcoins from this time are from block 9.

Edit. I will now ignore blocks from satoshi's mining pattern completely for now.

Edit. Block 235 is spent.

Edit. Block 268 is spent.
The transaction is grouped with four other coinbases.

Edit. Block 309 is spent.
The transaction is grouped with a shitton of other coinbases.

Edit. Block 317 is spent.

Edit. Block 320 is spent.

Edit. I checked the other coinbases linked in the transaction with the reward from block 268.
The coins were all sent to one address: 19QKDUJtx9n7Vaga6nX1bVHdsnT4Khfyi
They have not moved since, but this implies that they were all mined by the same person.
Blocks 268, 417, 431, 442 and 450 were all mined by the same pseudonymous entity,
which I will hereon refer to as Vaga (it's in the middle of the address).

Edit. The extraNonces of the blocks mined by Vaga are all larger than the last. Could this incremental extraNonce not be exclusive to Satoshi?

Edit. I will now look closer at the transaction block 309's coins were involved in: a1be8f4fd67f305bbdd03be77104dda20680b934f12acb66c239a944bd5cb798

Edit. The renown 12higDjoCCNXSA95xZMWUdPvXNmkAduhWv is included in this transaction. Whoever mined block 309 probably owned that address.

Edit. I've linked the address to I)ruid. This means he mined block 309.

Seriously this is insane. I'm just going to wait until I have a better method.
