If you know the story of Apple, you may remember a moment when Steve Jobs offered to sell the Apple II to Commodore, the popular consumer electronics company that made its name selling trumped up calculators. Of course, Jack Tramiel, the head guy at Commodore turned down Jobs offer, and decided that his team should build its own personal computer. The result was the Commodore PET. Built on the same idea computer-as-appliance idea Jobs had for the Macintosh, the PET was supposed to be a computer you could use right out of the box, without having to attach or install anything. Despite selling well during its six-year production run, very few people remember the PET.
