The A2000, also known as the Commodore Amiga 2000, was released in 1987 (around the same time as the low-end high-volume model A500). Although aimed at the high-end market it was technically very similar to the A500, so similar in fact that the A2000B revision was outright based on the A500 design. What the A2000 had over the A500 was a bigger case with room for five Zorro II proprietary expansion slots, two 16-bit ISA slots, a CPU upgrade slot, and a battery-backed clock.
It should also be noted that, like the Amiga 1000 and unlike the Amiga 500, the A2000 came in a desktop case with a separate keyboard. The case was all in all more like that of the PC than that of the A1000, in that it lacked the open space underneath for hiding away the keyboard.
The A2000 was eventually succeeded by the Amiga 3000 in 1990.
