Someone dropped a lot of money on an Apple computer on Wednesday, and it has nothing to do with the fancy new 5K Retina iMac. In fact, the computer was built in 1976.

An Apple-1 computer — which was among the first computers developed by Apple — sold for $905,000 at a Bonhams New York auction, almost twice its highest estimate, according to the Bonhams auction house in New York City.

The antique computing device was built by Steve Wozniak in Steve Jobs' family garage, or debatably his sister's bedroom, almost four decades ago. The Apple-1 spurred the onslaught of the personal computer that would transform Apple into the massive tech company it is today.

A representative from the Henry Ford Museum clutched the winning bid. The museum chronicles tech breakthroughs and innovation in the United States.

This is one of the first 50 Apple-1 computers, which Jobs and Wozniak built for electronics retailer Byte Shop. The computers first sold for $666.66 — a tiny fraction of the price the computer went for this week. The auctioned-off Apple-1 includes an intact motherboard, vintage keyboard and monitor and a custom wooden-box power supply.

Apple-1s are extremely rare, and buyers pay good money to get their hands on them. Last year, an Apple-1 sold for $671,400 in Germany to an anonymous entrepreneur identified only as from the "Far East".
