Any computer scrap/surplus shops worth visiting?

I'm coming to SF for a few days next month, and am a bit of a retrocomputing enthusiast. Obviously, one of the first items on my itinerary is the Computer History Museum, but is there any place worth visiting if I want vintage-computing souvenirs, not just photographs?

On my last holiday, I went to Toronto and ended up spending a day heading out to the fringes of the city and rooting a scrap dealer's boxes for ISA cards instead of exploring culture, art, or history. :)

I know I should have shown up 10 years ago if I wanted to see the heyday of scrap dealers, but linear time and all. :P

Someone mentioned Anchor Electronics in Santa Clara, but I'm staying downtown and it looks like it's 2 hours each way from there via public transport, and even an hour plus from the CHM. I suspect getting a Waymo may cost a fortune if they'd even cover that area... I try not to be in cars when on holiday, but I can sort of make an exception for a technological novelty.
