... but it could also be that his PC is just that slow and unstable to find a block. CPU miners were fairly unstable and slow, even for 1 difficulty blocks especially how optimized it was.
Regardless, the nonce of the block is pretty special and follows a specific pattern. Jlopp has a nice writeup here:
https://blog.lopp.net/was-satoshi-a-greedy-miner/Your assumption that Satoshi's mining computer(s) were slow and unstable is not quite supported by the findings around extra nonce values and their distribution and interpretation given by Lopp and Sergio Demian Lerner[1].
Have a look at the miner attribution displayed here
https://bitcoinexplorer.org/blocks?limit=25&offset=0&sort=asc.
The graph at [1], the steeper slope of the dark blue colored dots can be interpreted that "Patoshi" had rather potent mining gear (computers, very likely not a single computer).
I'm with Sergio and his findings/modeling and believe that blocks attributed to the miner "Patoshi" are actually mostly those that Satoshi mined.
I don't know if the Patoshi blocks list has been updated (minor corrections are likely needed as there are spends from a few Patoshi attributed blocks that very certainly haven't been done by Satoshi, ie. the attribution must be wrong for those) because when I created a descriptor wallet that covers all output address types for the public keys of those coinbases, some spends in higher numbered blocks showed up that to almost certainly can't have been from Satoshi (very highly unlikely).
It was a fun project I started around the end of 2021 for a Bitcoin Core wallet with 21954 combo-descriptors; it was much less fun to sync it with older versions of Core because it literally took ages (many months!) on energy efficient hardware. I didn't want to waste too much energy than necessary and ran it on already running Raspi that powered one of my nodes. Poor little Raspi...
