The Apple III was first introduced at the National Computer Conference in September of 1980. The Apple III , originally code named “Sara”, sported a brand new operating system with a built in disk controller and 4 peripheral slots. Since floppy disks were used all the time for loading and unloading information from the computer, this was very handy. The original price tag for the Apple III was $3,495 – the priciest product yet for Apple.
