Staff writer Teresa Mendez talks about her trip back in time, looking at the beginning of the PC generation.

Preserving the cutting edge

By contrast, the Computer History Museum, 30 miles north, is a much vaster and more comprehensive collection. Here, a sign reads: "Thank you for not touching the artifacts."

The museum (also free and open most afternoons) has a complex history that began outside Boston in 1979. In 2002, it moved to its new space, the former home of Silicon Graphics – itself an artifact of the computer age.

Curator Alex Bochannek dons white gloves for a tour of the restoration lab, where volunteers have reassembled an IBM 1401 system – one of those early, sprawling series of machines that occupy an entire room.

"Visible Storage," the museum's main exhibit, spreads throughout a cavernous space like a warehouse. It holds more than 600 items – only a portion of the museum's collection. A comprehensive computer timeline is being assembled to be unveiled in 2009. But for now, the Babbage Engine is the museum's star.

"Silicon Valley, and the technology industry, tends to be a community that drives with no rearview mirror," says Nathan Myhrvold, a former CTO of Microsoft who funded the Engine's construction. "As a result it's very rare to see people ... conserve or honor or display old computers."

 

A Silicon Valley roadtrip

The computer may not seem like the most aesthetic of museum relics. But for technology lovers and neophytes alike, it offers a fascinating and nostalgic window onto contemporary culture. These museums and sites, dedicated to technology in all forms, are within driving distance of each other. Together they’d make for a nice weekend of technology.

Before the printers and the laptops, Bill Hewlett and Dave Packard tinkered in a garage behind 367 Addison Avenue. Now a California Historic Landmark, the garage was renovated in 2005 and bears a plaque that declares it “The Birthplace of ‘Silicon Valley.’ ”

Visitors cannot wander the property, but the garage can be seen from the road.
