They were designed and hand-built by Steve Wozniak.〔(NPR : A Chat with Computing Pioneer Steve Wozniak )〕 Wozniak's friend Steve Jobs had the idea of selling the computer. The Apple I was Apple's first product, and to finance its creation, Jobs sold his only means of transportation, a VW Microbus,〔(Kelley: Jobs' vision changed the way we work, play )〕 and Wozniak sold his HP-65 calculator for $500.〔(Steve Jobs: Steve Wozniak Remembers )〕 It was demonstrated in July 1976 at the Homebrew Computer Club in Palo Alto, California. ==History== On March 5, 1975 Steve Wozniak attended the first meeting of the Homebrew Computer Club in Gordon French's garage. He was so inspired that he immediately set to work on what would become the Apple I computer. Wozniak calculated that laying out his design would cost $1,000 and parts would cost another $20 per computer; he hoped to recoup his costs if 50 people bought his design for $40 each. His friend Steve Jobs arranged to sell 50 computers to the Byte Shop (a computer store in Mountain View, California) at $500 each. To fulfill the $25,000 order, they obtained $20,000 in parts at 30 days net and delivered the finished product in 10 days. The Apple I went on sale in July 1976 at a price of , because Wozniak "liked repeating digits" and because of a one-third markup on the $500 wholesale price.〔Wozniak, Steven: "iWoz", page 180. W. W. Norton, 2006. ISBN 978-0-393-06143-7〕 The first unit produced was used in a high school math class, and donated to Liza Loop's public access computer center. About 200 units were produced and all but 25 were sold during nine or ten months. Unlike other hobbyist computers of its day, which were sold as kits, the Apple I was a fully assembled circuit board containing about 60+ chips. However, to make a working computer, users still had to add a case, power supply transformers, power switch, ASCII keyboard, and composite video display. An optional board providing a cassette interface for storage was later released at the cost of $72. The Apple I's built-in computer terminal circuitry was distinctive. All one needed was a keyboard and an inexpensive television set. Competing machines such as the Altair 8800 generally were programmed with front-mounted toggle switches and used indicator lights (red LEDs, most commonly) for output, and had to be extended with separate hardware to allow connection to a computer terminal or a teletypewriter machine. This made the Apple I an innovative machine for its day. In April 1977 the price was dropped to $475.〔(April 1977 Price List | Applefritter )〕 It continued to be sold through August 1977, despite the introduction of the Apple II in April 1977, which began shipping in June of that year.〔(Bill of Sale | Applefritter )〕 Apple dropped the Apple I from its price list by October 1977, officially discontinuing it.〔(October 1977 Price List | Applefritter )〕 As Wozniak was the only person who could answer most customer support questions about the computer, the company offered Apple I owners discounts and trade-ins for Apple IIs to persuade them to return their computers〔(【引用サイトリンク】 title=The Apple II, cont. )〕 These recovered boards were then destroyed by Apple, contributing to their rarity today.〔(【引用サイトリンク】 title=The Huston brothers' Apple-1 Back Story )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Apple I」の詳細全文を読む スポンサード リンク
