The State of Software
Unix was written in a machine independent language. So Unix and unix-like operating systems can run on a variety of hardware. These systems are available from many different sources, some of them at no cost. Because of this diversity and the ability to utilize the same “user-interface” on many different systems, Unix is said to be an open system.
Of all the computers that Apple has ever made there’s only one that Steve Jobs had to sell his car to finance — It was sold for $905,000 in 2014 at the auction.
The Apple-1, as the machine is known, is one of fifty hand-assembled by Apple co-founder Steve Wozniak in Jobs’ family garage in 1976. It was the first pre-assembled computer ever made (they usually came as kits) and is credited by many tech historians as kick-starting the PC revolution.
