UPDATE from Woz received on Aug 04, 2010:
"The Apple I boards were manufactured and populated with components (sockets for the chips) and wave soldered at some company in Santa Clara. Those boards were driven to the house, and later the garage, where we inserted the chips and tested them. We did no soldering there.
My development work was all done in my apartment in the Villa Serra complex on Homestead Road, between Mary and Stelling. Also, much was done in my cubicle at HP's calculator division (APD) which was then in Cupertino, on Pruneridge Avenue (19925?) slightly East of Wolfe Road."
