Aimed at the high-end market, the original Europe-only model adds a Zorro II backplane, implemented in programmable logic, to the custom Amiga chipset used in the Amiga 1000.
Later improved models have redesigned hardware using the more highly integrated A500 chipset, with the addition of a gate-array called "Buster", which integrates the Zorro subsystem.
This also enables hand-off of the system control to a coprocessor slot device, and implements the full video slot for add-on video devices.

Like the earlier model, the Amiga 1000, and most IBM PC compatibles of the era, but unlike the Amiga 500, the A2000 comes in a desktop case with a separate keyboard.
The case is taller than the A1000 to accommodate expansion cards, two 3.5" and one 5.25" drive bays.
The A2000's case lacks the "keyboard garage" of the Amiga 1000 but has space for five Zorro II expansion slots, two 16-bit and two 8-bit ISA slots, a CPU upgrade slot and a video slot.
Unlike the A1000, the A2000's motherboard includes a battery-backed real-time clock.

The Amiga 2000 offers graphics capabilities exceeded among its contemporaries only by the Macintosh II, which sold for about twice the price of a comparably-outfitted Amiga 2000 additionally equipped with the IBM PC Compatible bridgeboard and 5.25" floppy disk drive (which was important for real-world interoperability at this time).
Also like the A1000, the A2000 was sold only by specialty computer dealers.
It was originally announced at a price of 1495 USD
The A2000 was largely succeeded by the Amiga 3000 in 1990.
The 3000 features fewer options for internal expansion than the 2000 models, so Commodore supplemented the Amiga 3000 with the Amiga 3000T in 1991.
