Apple I

Apple I. The Apple I was the first product released by the nascent Apple Computer Company, designed primarily by co-founder Steve Wozniak. Introduced in 1976, it was a bare printed circuit board that hobbyists could assemble into a working computer, marking a pivotal step in the transition from minicomputer kits to pre-assembled personal computers. Its debut at the Homebrew Computer Club and subsequent limited commercial success provided the capital and credibility for the development of the revolutionary Apple II.

Development and design

The Apple I was conceived by Steve Wozniak while he was an employee at Hewlett-Packard and a regular attendee of the Homebrew Computer Club in Menlo Park, California. His design philosophy emphasized simplicity and cost-reduction, leveraging his experience with earlier projects like the Cream Soda computer and his work on *Breakout* for Atari. Wozniak's friend Steve Jobs recognized its commercial potential and convinced him to market the board. The pair funded initial production by selling Jobs's Volkswagen Type 2 van and Wozniak's HP-65 calculator. The design was notable for its use of the inexpensive MOS Technology 6502 microprocessor and its integrated keyboard interface, which distinguished it from contemporaries like the Altair 8800 that required complex front-panel programming.

Technical specifications

At the heart of the Apple I was the 8-bit MOS Technology 6502 microprocessor running at 1.0227 MHz. It came standard with 4 KB of dynamic RAM, expandable on-board to 8 KB using Intel or Motorola memory chips; through an expansion connector, memory could be increased to 48 KB. For output, it generated a composite NTSC video signal, displaying 40 columns by 24 lines of uppercase text. Unlike many kits, it included a built-in ROM bootstrap routine and a terminal program, so it was operational upon power-up when connected to a Sanyo or Panasonic monitor. Storage was achieved via a cassette tape interface, and the entire system required only a +5V power supply. Its printed circuit board was elegantly laid out by Wozniak, featuring approximately 30 integrated circuits.

Production and sales

The first production run of about 50 units was hand-assembled by Wozniak, Jobs, and early employee Daniel Kottke in the garage of Jobs's family home in Los Altos, California. In July 1976, the computer was offered for sale at a price of US$666.66 through the newly formed Apple Computer Company. The primary retailer was the pioneering Byte Shop in Mountain View, California, owned by Paul Terrell, who ordered 50 fully assembled units. In total, approximately 200 Apple I computers were produced before it was discontinued in September 1977 to make way for the Apple II. A significant number of units were later traded back to the company, often as part of an upgrade program for the newer model.

Historical significance

The Apple I is historically significant as the product that launched Apple and demonstrated the viability of a pre-assembled, easy-to-use microcomputer for a broader audience beyond hardcore electronics enthusiasts. Its presentation at the Homebrew Computer Club showcased a machine that was more complete and user-friendly than the MITS Altair. The profit from its sales, though modest, provided the essential seed capital to finance the development and manufacturing of the Apple II, which would become one of the most successful personal computers of all time. Furthermore, it established the foundational partnership and business acumen of Steve Jobs and the engineering genius of Steve Wozniak.

Legacy and preservation

Today, the Apple I is an extremely rare and valuable collector's item, with functioning units fetching high prices at auctions conducted by houses like Christie's and Sotheby's. Institutions such as the Computer History Museum in Mountain View, California and the Smithsonian Institution preserve examples for public display. Its legacy is celebrated as the tangible genesis of the Apple empire, inspiring replicas and emulators for modern enthusiasts. The original design documents and schematics, along with stories from the Homebrew Computer Club, are studied as seminal artifacts of the Silicon Valley revolution that transformed technology and global culture.
