Until six months before its launch in January 1984, Apple's Mac had a 5.25-inch floppy-disk drive, but because of high error rates, that device had to be replaced by a Sony 3.5-inch drive.
The 128K Macintosh
When the Mac was introduced, it came with no hard disk, just a 3.5-inch floppy drive manufactured by Sony. Thus began the manual art of disk swapping.
Mr. Macintosh, seen here at the left side of the circuit board, was a mysterious little guy who was supposed to live inside each Macintosh, as represented in a drawing by the Belgian artist Jean-Michel Folon, commissioned by Steve Jobs.
Motherboard and daughter boards
The original concept for the Macintosh, conceived by Jef Raskin, was more horizontal and portable. When Jobs took over the project, he reoriented it vertically so it would more easily fit on a desk.

Back of the Mac
For Steve Jobs, the look and finish of the back of the Macintosh was just as important as that of the front.

Dan Kottke, Apple employee No. 12
Dan Kottke helped assemble and test the first Apple I with Steve Wozniak in Steve Jobs' family garage in 1976. He also worked on the Mac hardware.
Chris Espinosa: Apple employee No. 8
Chris Espinosa started working at Apple when he was 14, and continues to work at the company to this day.

While Andy Hertzfeld (right) was working on operating system software and other elements to get the Macintosh to market , Guy Kawasaki was serving as the chief evangelist for the new machine that would shake up the world.
Apple Computer drawing paper
Lead industrial designer Jerry Manock was excited by the fact that his boss Steve Jobs allowed him to design his own drawing paper.
The Macintosh hardware trio: Holt, Nicholson, Kottke
Rod Holt was vice president of engineering during the early years of Apple, and worked on the Macintosh power supply; Ron Nicholson worked on the Mac's disk controller and CMOS clock chip; and Dan Kottke joined the Mac team in 1981, building prototype circuit boards for programmers.

Larry and Patti Kenyon
The Kenyons were a core part of the original Mac team. Patti left the company until shortly after the Macintosh shipped and Larry stayed at Apple until 1996.

Rod Holt: Apple hardware guru
Rod Holt worked at Atari, where Steve Jobs also briefly worked. When Jobs was having trouble with Apple II hardware, he managed to get the very experienced Holt to help out. He joined Apple in 1976 and left in 1984.
Wendell Sander: Designer of the Integrated Woz Machine
Wendell Sander was the designer of the Apple III, and created a single chip that included all the functionality Woz's disk controller. It was called the "IWM" chip, which stood for the "Integrated Woz Machine."
