The Apple I, or rather Apple Computer I is a desktop computer created in 1976 by Apple Computer. The originator and creator of the computer was Steve Wozniak. Steve Jobs – Wozniak’s friend came up with a brilliant idea to create a company and start selling computers. It quickly turned out that Apple had to find the money for production to make more computers. Jobs sold his car, and Wozniak his programmable HP-65 calculator.

Apple I went on sale on April 11, 1976, for $666.66. The company produced two hundred pieces of this computer. It is worth noting that, unlike other computers sold at the time for hobbyists in the form of “Do it yourself”. Apple I was already fully assembled. Nevertheless, to get a fully functional computer, its buyers had to add a case, power supply, keyboard, and monitor. Apple I was the first publicly available computer to use a monitor and a keyboard.

Apple Computer 1 ran Apple Integer BASIC, a programming language developed by Steve Wozniak, especially for Apple 1. Apple’s first computer promised flexibility, performance, and ease of use. It packed a 1 MHz 8-bit MOS Technology 6502 microprocessor, 4 kilobytes of RAM, and 1 kilobyte of Graphic memory, which was huge at the time. There was no internal storage, no keyboard, no display, and other peripherals.

The Apple I successor was the Apple II model. It went on sale on 16 April 1977 and, unlike its predecessor, it had housing and a keyboard. Today Apple I is 48 years old!
