It's cool how "intel" (bottom right) and "FF" [1] (top right) is signed using the same process as the rest of the chip :D
[1] initials of Federico Faggin
The whole exercise does seem like Faggin, Shima and Mazor trying to produce the chip with little help from the rest of Intel.
I think given the target market though the speed wasn't a major issue and they soon rectified the mistake
