Not the answer I'm looking for.

Ivy League Universities are on the other side of the US, they were more prestigious even back then. At the time the IT companies were setting up shop in California, there were virtually no Universities destined to grew computer guys there. It was a virgin field in so many ways.

In short, this is not the reason Silicon Valley was chosen to be in California, in the particular place. I'll ask again some other time since it's probably too early (for my reach anyway).
