Submitted by binaryvalue on Wed, 06/01/2022 - 13:08

 Released in March 1987, the Commodore Amiga 2000 is a multi-featured business machine based on the MC68000 CPU. The A2000 features OCS hardware graphics, PCM stereo sound, multitasking, and a GUI. The model was discontinued in 1991, shortly after Commodore released the Amiga 3000. The A2000 is a very expandable computer and the first Amiga with a Zorro II bus. It was designed with an open architecture, something that led several government organizations, such as NASA, to use it for various tasks.

  • Initially, the A2000 was sold for $1,495 (around $3,800 in today’s money)
  • Several artists and TV studios used the A2000 (due to its multimedia capabilities and the iconic Video Toaster card)
