The launch of the Apple II at the West Coast Computer Faire on the 16thApril 1977 marked the birth of the personal computers industry. Interestingly on the same day, Commodore PET 2001 computers were also launched.
The irony of the situation can be seen from the fact that previously Commodore had previously rejected purchasing the Apple IIfrom Steve Jobs and Steve Wozniak, and had decided to build their own computers.
Apparently both computers used the same processor, the MOS 6502, but the companies had two different design strategies. As Apple wanted to build computers with more features at a higher price point, meanwhile Commodore wanted to sell less feature-filled computers at a lower price point. Therefore, the Apple II had color, graphics, and sound selling for $1298. The Commodore PET only had a monochrome display and was priced at $795.
