The address given for the Byte Shop, "1063 El Camino Real in Mountain View", is ambiguous. It needs to specify either 1063 EAST El Camino Real or 1063 WEST El Camino Real, two quite different locations.
Neither of those matches the store that I remember patronizing circa 1978 or so, to buy a California Computer Systems S-100 box. That would have been on El Camino just north of Grant Road, circa 80 W El Camino.
It’s West. If you look at google maps for that location, there is a landmark pinned for “The Original Byte Shop”. There you can see a B&W photo from back in the day.
