I came to the valley (no, the other one, up north) back around 1995. And Weird Stuff was absolutely one of the things that made it "Silicon" valley.
Back when I would BBS from Kansas and pore over text files listing BBS's I was green with envy at all the boards in Sunnyvale, Mountain View....
Coming out here was everything I had imagined when I walked into Fry's, Weird Stuff, Disk Drive Depot, The Computer Literacy Bookstore, Haltek Electronics....
Slowly though the hardware Mecca that was the valley gave way to the internet titans and software as Yahoo, Google, etc. appeared.
Fry's started selling T.V.s mainly.
The Saturday morning electronics surplus crawl that used to include a half-dozen stops became just HSC....
Weird Stuff moved out near the Sunnyvale dump.
The pizza dive on Steven's Creek that Woz loved became Pizza and Noodles, then just Falafels.
Vivi's is gone.
When the Donut Wheel closes shop it will be time for me to move on.
