  • The Apple® I was a kit sold as a motherboard, was the first product, and was introduced in April 1976 andput on sale in July of 1976 with a 1 MHz MOS 6502 processor and 4 kB of RAM. About 200 units were produced and sold for $666.66.
  • The Apple II® went on sale on June 5, 1977 with the same processor as the Apple® I. It sold for $1,298 for the basic unit and needed a TV to use as a monitor. The Apple II® displayed the multicolor Apple® logo which was used until 1998.
  • The Apple III® was introduced in May 1980 with a 2 MHz Synertek 6502A processor at a price of $3,500. Problems with early models such as overheating killed sales. An updated model in 1983 was a failure due to its poor reputation. About this time IBM and Microsoft were taking the lead in the personal computer business. Apple® hung on by maintaining a close relationship with schools.Apple III

It was written to work on Mac OS® X, but it does not take advantage of many of the newer features of Mac OS® X. AppleWorks can create, open, and save files in a number of file formats. For example, word processor documents can be saved in Word format, and spreadsheet files can be saved in Microsoft Excel format. Although AppleWorks for Mac OS® X is available for purchase, it is no longer bundled with new Macintosh® computers and has not been updated since 2004. Apple® considers that iWork® will eventually be a replacement for AppleWorks, but iWork® does not include drawing or database features.
