Many thanks for the nice comments.
@ D-D
I met him through a CL add offering to pickup old electronics gathering dust etc. It was definitely my coolest E-cycling adventure yet. He lived in a beautiful home cantilevered off the side of a mountain near the UC Berkeley campus -- very cool views of Oakland, the Bay and San Francisco. He was (or maybe still is) an engineer/scientist at the UC Berkeley Space Science Laboratory (SSL) -- the address was listed on many of the old boxes he gave me. SSL is a fascinating institution that does NASA/military research. Edward Teller was one of the first lab directors in the late 1950s.

I have no idea why he gave me all this stuff. I guess he just wanted to clean out the house.
@ Miked
He gave me boxes of stuff and 15 of these chips were stored in a couple of special static-free trays.
I'll take some photos of some other stuff in the boxes.
I also posted over at the CPU-World forum to get some insights about these chips. In about 10 minutes I got an interesting tidbit of info from a guy in Estonia.
They are apparently static RAM (SRAM) chips made during week 26 of 1977.

The web has made communication/info-sharing so awesome.
I've only been doing E-cycling for a couple of weeks, but Silicon Valley seems to be a wonderfully rich area for this sort of thing.
