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.
The Lisa is a rare GUI-based business computer released by Apple Computer, Inc. in 1983. There are two editions (Lisa I and Lisa II), while Lisa 2/10, was modified and later released as the Macintosh XL. The Lisa computer was more advanced than the later Macintosh 128/512K but it was far more expensive. Lisa 1 was sold for $9,995 which means around $29,000 in today’s money. Lisa 2 was less expensive.
It is estimated that around 10,000 Lisa units were sold (only 500 Lisa 1)
