California museums tell the history of computing
Bit by bit, they gather and display gadgets from the computer revolution.

Charles Babbage's Difference Engine No. 2, one of the earliest computers, has just arrived for display May 10 at the Computer History Museum here in Mountain View. It existed only on paper for more than 150 years until, in 2002, Doron Swade and a small team assembled the five-ton computer from 8,000 bronze, iron, and steel parts.
On one side is a hand crank, on the other a spool of paper to print answers to the polynomial functions used by navigators and astronomers. Between lies the heart of the engine, rising like a gigantic abacus whose beads are interlocking gearwheels, each representing a digit. As Mr. Swade turns the machine's crank, gear teeth propel gear teeth in a whirling dervish of additions.
"By exerting physical energy, you could get results that, up until that point in time, were only achieved by mental effort," says Swade. "This was the first successful transfer of human intelligence to a machine."
The rest is computing history.
Nestled in this expanse of office parks and in the nearby mountains are two museums dedicated to preserving the history of Silicon Valley's computing culture. There's some overlap between the Computer History Museum and the considerably more informal DigiBarn Computer Museum set in the mountains outside Santa Cruz. What's different are their presentations and curatorial philosophies. Together, they make for a very nice pairing.
PCs put out to pasture
When DigiBarn curator Bruce Damer found himself in possession of a 19th-century farmstead in 1998, he was at a loss for what to do with the two-story red barn. For a self-described "nerd with a 5,000-square-foot barn," the logical answer, it seems, was to pack it with vintage computer technology. (Admission is free, but by appointment only made through its website: digibarn.com.)
Inside, the shaded windows give the light a muted, slightly dingy cast. Tables, some covered in red-checked cloths, heave with monitors, keyboards, and hard drives.
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.
The Computer History Museum
Mountain View, Calif.
Microcomputers, supercomputers, and everything in between. The vast and comprehensive collection includes a 600-piece permanent display and rotating special exhibits.
Open Wednesday, Friday, Saturday, and Sunday afternoons. Admission is free.
The DigiBarn Computer Museum
In the Santa Cruz Mountains
The contents of this private barn track the evolution of the personal computer. With pigs outside and computers inside, the quirky contrast is worth the effort of an appointment and the strikingly winding mountain drive.
Tours are free, but only by appointments made through its website.
San Francisco, Calif.
Hundreds of interactive exhibits blend science, art, and technology. Dedicated to both entertaining and educating visitors, the museum hosts numerous events, including the upcoming CSI: Toys, where kids use forensic science to help solve mysteries.
Open Tuesday through Sunday. Admission is $14, with special deals for students and children.
The Intel Museum
Santa Clara, Calif.
Nestled in Intel’s headquarters, the museum guides you through the history of the company and computer innovation. Interactive displays highlight the science and labor that go into making PCs.
Monday through Saturday. Admission is free.
The HP Garage
Palo Alto, Calif.
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.
