The A2000, also known as the Commodore Amiga 2000, was released in 1986. Commodore, the commonly used name for Commodore International, was a US-American Electronics company based in West Chester Pennsylvania The Amiga is a family of Personal computers originally developed by Amiga Corporation. Year 1986 ( MCMLXXXVI) was a Common year starting on Wednesday (link displays 1986 Gregorian calendar) 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. Zorro II is the name of the general purpose expansion bus used by the Amiga 2000 computer Industry Standard Architecture (in practice almost always shortened to ISA) was a Computer bus standard for IBM compatible computers

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 A1000, or Commodore Amiga 1000 was Commodore's initial Amiga Personal computer, introduced on July 24, 1985 at the 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. The A3000, also known as the Commodore Amiga 3000 was a much more serious proposition to build a professional multimedia computer than the previous A2000
