Aimed at the high-end market, the Commodore Amiga 2000, is a personal computer released by Commodore in March 1987. The Amiga 2000 is the first Amiga model that allows expansion cards to be added internally. SCSI host adapters, memory cards, CPU cards, network cards, graphics cards, serial port cards and such. The Amiga 2000 was designed with an open architecture, Commodore was so successful at this that Info magazine judged that the A2000 would not become obsolete “until well after the turn of the century” at the earliest. As one of the most powerful of it’s time, the US army department adapted 4 Commodore Amiga 2000s from 1988 to 1991 to develop the digital displays panels installed in the M1A2 Abrams Main Battle Tank built by General Dynamics Land Systems. In the General Dynamics Simulation Laboratory, the Amigas interfaced with a central simulation environment computer and produced graphics for the display panels.
