The A2000, also known as the Commodore Amiga 2000, was released in 1986. 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 and two 8-bit ISA slots, a CPU upgrade slot, a video 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 more PC-like than the A1000 - taller to accommodate the expansion cards and lacking the space beneath for the keyboard.
The A2000 was eventually succeeded by the Amiga 3000 in 1990.
