In 1976, Wozniak started attending meetings of the Homebrew Computer Club. New microcomputers such as the Altair 8800 and the IMSAI inspired him to build a microprocessor into his video terminal and have a complete computer.
At the time the only microcomputer CPUs generally available were the $179 Intel 8080 ($773.00 in present-day terms), and the $170 Motorola 6800 ($734.00 in present-day terms). Wozniak preferred the 6800, but both were out of his price range. So he watched, and learned, and designed computers on paper, waiting for the day he could afford a CPU.
When MOS Technology released its $20 ($82.00 in present-day terms) 6502 chip in 1976, Wozniak wrote a version of BASIC for it, then began to design a computer for it to run on. The 6502 was designed by the same people who designed the 6800, as many in Silicon Valley left employers to form their own companies. Wozniak's earlier 6800 paper-computer needed only minor changes to run on the new chip.
Wozniak completed the machine and took it to Homebrew Computer Club meetings to show it off. At the meeting, Wozniak met his old friend Jobs, who was interested in the commercial potential of the small hobby machines.
The Apple I was sold as an assembled circuit board and lacked basic features such as a keyboard, monitor, and case. The owner of this unit added a keyboard and a wooden case.
The very first Apple Computer logo, drawn by Ronald Wayne, depicts Isaac Newton under an apple tree.
The Apple logo in 1977 created by Rob Janoff with the rainbow color theme used until 1998. Steve Jobs and Steve Wozniak had been friends for some time, having met in 1971, when their mutual friend, Bill Fernandez, introduced 21-year-old Wozniak to 16-year-old Jobs. Jobs managed to interest Wozniak in assembling a machine and selling it.
Jobs approached a local computer store, The Byte Shop, who said they would be interested in the machine, but only if it came fully assembled. The owner, Paul Terrell, went further, saying he would order 50 of the machines and pay US $500 ($2.04 thousand in present-day terms) each on delivery. Jobs then took the purchase order that he had been given from the Byte Shop to Cramer Electronics, a national electronic parts distributor, and ordered the components he needed to assemble the Apple I Computer. The local credit manager asked Jobs how he was going to pay for the parts and he replied, "I have this purchase order from the Byte Shop chain of computer stores for 50 of my computers and the payment terms are COD. If you give me the parts on a net 30 day terms I can build and deliver the computers in that time frame, collect my money from Terrell at the Byte Shop and pay you."
With that, the credit manager called Paul Terrell who was attending an IEEE computer conference at Asilomar in Pacific Grove and verified the validity of the purchase order. Amazed at the tenacity of Jobs, Terrell assured the credit manager if the computers showed up in his stores Jobs would be paid and would have more than enough money to pay for the parts order. The two Steves and their small crew spent day and night building and testing the computers and delivered to Terrell...
