The Apple Computer 1, or Apple I, is an 8-bit desktop computer created by the Apple Computer Company in 1976. It was designed by Steve Wozniak.

Together with Steve Jobs, Wozniak's friend, the pair decided to try and sell the computer. To finance the manufacturing, Jobs sold his VolksWagen Microbus, and made a few hundred dollars. Wozniak sold his HP-65 calculator for $500, and the pair had enough money to produce a prototype for show at the Homebrew Computer Club in Palo Alto, California.

In 1977 the company produced the Apple II, which is referred to as being part of the 1977 Trinity of computing together with the Commodore PET 2001 and the TRS-80 Model 1 from the Tandy RadioShack company.

The 6502 is an 8-bit MicroProcessor designed by MOS Technology. The team was led by Chuck Peddle and had also worked on the Motorola 6800. The 6502 is a simplified, but faster and cheaper design than the 6800.

The 6502 was introduced in 1975 and was the cheapest microprocessor on the market. Together with the Zilog Z80, the 6502 helped start the home computer revolution of the 1980s. The 6502 was used in a wide range of devices: the Atari 2600, the 8-bit Atari home computers, the Apple II, the Nintendo Entertainment System, the Commodore 64, the BBC Micro and many others. All used the 6502 or a variation of it.

The 6502 is a 1MHz design, while the 6502A is designed for 2MHz. The 6502A is 100% compatible with the original 6502.

Commodore soon bought MOS Technology, but conitnued to sell the microprocessor to competitors and licensed the design to other manufacturers.
