Silicon Valley in Northern California is home(1) to many of the world’s largest technology companies(2). These include Apple, Google, Oracle, Intel, Cisco Systems and Hewlett-Packard. The valley is also(3) home to the Computer History Museum in Mountain View.

It reopened(4) in December after nineteen million dollars worth(5) of improvements(6).One of the additions is a permanent exhibit called “Revolution: The First 2000 Years of Computing(7).”Alex Bochannek is a curator(8) at the museum. Mr. Bochannek says the new exhibit(9) tells the story of more than one thousand historical objects.

He said: “Some of the oldest(10) items are actually(11) not computers. They are devices(12) that helped people calculate. And the first object people see walking into the exhibit is an abacus from the eighteen hundreds.

Because the abacus is a daily-use(13) device made from wood(14), few of them(15) have survived(16).” Mr. Bochannek says people have the chance to handle(17) some of the objects in the exhibit.

He says one of the more popular items is a portable computer(18) from nineteen eighty-one. The Osborne One was about the size(19) of a sewing machine(20) and weighed(21) more than ten kilograms.

So, just being able to(22) pick one of those up(23) will help visitors(24) understand how difficult portability(25) was about thirty years ago(26). Visitors to the Computer History Museum can also see parts of one of the earliest(27) large-scale electronic computing devices. The ENIAC or Electronic Numerical Integrator and Computer was designed(28) during World War Two(29).

There are also(30) pieces(31) from the guidance(32) computer that was used during the Apollo space missions. Mr. Bochannek says the “Revolution” exhibit is about more than the history of modern computing. He says it tells a much larger story(33) about how these developments have affected society and culture, especially in recent years.

He said the revolution to most people is that computers are everywhere(34). If you are crossing the street(35), there probably is(36) a computer controlling the traffic light(37).

Computers surround us(38). In some cases they are even(39) inside us(40), like the cardiac pacemaker(41) device in the exhibit. The Computer History Museum plans to launch(42) an online version of the exhibit in March. The museum has one hundred thousand items in its complete collection. Only two percent of them are currently(43) on display(44).

But officials say seventy-five percent of the items will be viewable(45) online. For VOA Special English I’m Alex Villarreal.
