The Apple Computer 1 or Apple-1, originally released as The Apple Computer and retroactively referred to as the Apple I, is a limited production kit computer that the Apple Computer Company introduced in July 1976 for US$666.66. This prototype computer was made for hobbyists and included a BASIC interpreter, extensive printed documentation, multiple I/O ports on the main PCB and the ability to create and add simple peripheral devices. The Apple I was the predecessor of the Apple II series which had the industry's first color graphics computers for consumers, and was the first computer sold by a predecessor company of Apple Inc.

Features

An early MOS MCS6502 processor, like the one that had been used in the Apple I.

Unlike the Apple II and other computers after it, the Apple I was sold as a populated circuit board kit with a MOS MCS6502 processor that the end-user had to assemble for themselves. Some hobbyists created custom cases for it in wood or plexiglass. Apple switched to providing metal and plastic casing for future models of their computers once they began to target the consumer market and not just computer club hobbyists.

Apple I components and setup.

Unlike the Apple II computer which came with Steve Wozniak's magnetic sector floppy disk drive, the Apple | came with no peripherals or storage, beyond the ROM chip holding the BASIC interpreter, the interface ROM, and 4Kb (expandable to 8Kb) RAM for storing running computer instructions.

In order to run software on the Apple I computer, a user had to connect a keyboard and a television, and then use the keyboard to input instructions in machine code or load the Apple BASIC programming language from a cassette tape.

History

Workspace in the garage of the home of Steve Jobs' parents, where the Apple I was assembled.

Future Apple co-founder Steve Wozniak designed the Apple I board around the MOS 6502 processor, for which he had written a BASIC interpreter. He completed the schematic by March 1, 1976.[1] Wozniak showed his hand-built prototype at a meeting of the Homebrew Computer Club on April 11.[2] He had built it with experience gained from building a simpler board, called the Cream Soda computer, in 1971.[3][4] Hewlett-Packard and Atari declined to acquire Wozniak's design, so Steve Jobs sold his Volkswagen Bus and Wozniak sold his HP-65 calculator to raise funds to make it themselves. Since Wozniak was still an employee of Hewlett-Packard, he obtained a release on May 5 to allow him to build the computers. Assembly began in a bedroom of the home of Jobs' parents, then moved into the garage when they ran out of space. Jobs enlisted his sister Patty and friend Daniel Kottke to help assemble the boards.[1][5]

Legacy

Production of the Apple I hobbyist kit was halted in September 1977, following the successful launch of the Apple II computer in June 1977.[1]

The Apple I is considered the spiritual ancestor of the Raspberry Pi as the first hobbyist computer. As the first product of the Apple Computer Company, it was mostly sold to enthusiasts belonging to computer user groups on the Pacific coast of North America.

As of 2017, 63 of the devices have been confirmed to exist, 3 of which have been verified to still be functional. The proceeds from the Apple I project went to obtain investment funding and acquire office space, equipment and supplies needed to produce the consumer-oriented Apple II computer.
