Features: Apple-1 was world's first Personal Computer with monitor and keyboard access. It was delivered as a motherboard only, with the peripheral equipment - case, power supply transformers, power switch, ASCII keyboard, and composite video display - supplied by the user. As Apple-1 did not have an operating system, but a so-called "monitor program" that provided the interface between keyboard entry, CPU, memory and monitor exit, more sophisticated software system such as Basic had to be loaded on cassette; the cassette-interface card was offered by Apple as an optional addition.

Power Supplies: +5 Volts @ 3 amps, +/-12 Volts @0.5 amp and -5 Volts @ 0.5 amps. Input Power Requirements: 8 to 10 Volts AC (RMS) @ 3 amps, 26 to 28 Volts AC (RMS) Center-Tapped, 1A.

Interesting facts: In April 1976 three young entrepreneurs - Steve Jobs, Steve Wozniak ("Woz") and Ronald Wayne - founded the Apple Computer Company to sell a new kit-form personal computer, designed and hand-built by Steve Wozniak. He put together circuit boards for what would be called the "Apple-1", and Jobs sold them to a new computer store, the Byte Shop in Mountain View, California. Although the Apple-1 was not the earliest of the first generation PCs, it captured computer users' interest in an unprecedented way. Approximately 200 units were made. 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. Apple dropped the Apple I from its price list by October 1977, officially discontinuing it.
