A Brief History of the Apple I

The Apple-1, or rather the Apple Computer I is a desktop computer created 47 years ago by the Apple Computer Company.

The originator and creator of the computer were Steve Wozniak and Steve Jobs – Wozniak’s friend who came up with a brilliant idea to create a company and start selling computers.

It turned out very quickly that Apple needed to find funds for making more computers. Jobs has sold his car, and Wozniak has sold his programmable HP-65 calculator as well to afford expenses.

The 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”, the Apple I was already fully assembled.

Nevertheless, to get a fully functional computer, its buyers had to add a case, a power supply, a keyboard, and a monitor. The Apple I was the first publicly available computer to be used with a monitor and a keyboard.

The Apple Computer 1 ran Apple Integer BASIC, a programming language developed by Steve Wozniak, especially for the Apple 1. Apple’s first computer promised flexibility, performance, and ease of use.

It’s been packed with 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 no other peripherals.

The Apple II model was the successor of the Apple I. It went on sale on 16 April 1977 and, unlike its predecessor, it had housing and a keyboard.

Where You Can See the Apple-1 in Person

The Apple Computer 1 is right now a scarce piece of tech you can find. The last working units are mostly in museums or private collections. Because the Apple I’s are so rare and most of them don’t work, there are just a few places where working units of this computer are displayed to the public.

The Apple-1 can be seen in the United States, Australia, South Korea, the United Arab Emirates, Poland, Germany, and Great Britain.
