Apple I was a computer developed by Steve Wozniak in 1975. It sold for the price of $666.66 (around $2,800 in 2015 money). It was Apple's first product, and about 200 were sold. Of these 200, 63 are still known to exist, but only six are still in working condition.
The specs of the Apple I were quite typical for its time. It used a MOS 6502 processor at 1 MHz, and 4KB RAM (expandable to 8KB). However, the user needed to supply a keyboard and display. In 1977 it was succeeded by the Apple II.
