Once a month through the summer engineers and technophiles of by-gone technologies converge on the humble parking lots of De Anza Community College. A collection of the by-products of silicon valley is hauled and put up for sale for hard cash. The mass of wares is a sea of cast-off technologies, junked computer parts, jumbles of cables, bolts, tools, cases, vacuum tubes, and deprecated equipment from military surplus and all kinds of electronic equipment of yester-year.
