Edit: turns out Mr. Felt was linking something else entirely.
Here's what I've found so far: https://bitcointalksearch.org/topic/m.1834775
I have evidence the same computer AND JUST ONE mined blocks 1-10
(edit: or a group of computers turned on exactly at the same time)
Just look at the extranonce field in the coinbase field of the coinbase transaction. (this field is hidden in the input script)
The counter is monotonically incrementing at a constant pace. This is like a "fingerprint" of the computer that was mining.
Also this can be used to find how many computers/threads where mining at some time (until they get powered-off). Each thread has another monotonically incrementing ExtraNonce variable.
So from that we can infer Satoshi PC Resources. Those resources allowed him to mine a block with 32 leading zeros every 6 minutes.
Unfortunately, I can't find the actual thread as of yet.
Suffice to say, Franky is full of shit (who is honestly surprised?): Sergio Demian Lerner did work out (well, estimated using reasonable assumptions) how much hardware Satoshi used to mine the Genesis Block, although my memory of it being several machines may be wrong. Looking for the thread Sergio refers to in the quote above.
