133 was the original design target speed for the Pentium Pro
The architecture performed better then expected thus 133s never were released, they were able to release at 150+

New Old Stock. In other words, unused.

Dang, some time ago, I thought that $200 would be too much for this...
This QSpec is supposed to be common despite the unreleased speed and Es status...

The price has gone bananas!
This is one of the more "common" PPro ES... (I got mine in similar shape for ~$150 three-ish years ago)

| I’d hate to imagine how many have gone under a scrapper’s hammer to recover the gold top and pins. But I would imagine between that and the rise in chip collecting it might be a factor. |

A bit surprising about final price but everything is rising so why not CPUs should do ?
