Commodore Amiga A2500
The Amiga 2500 is basically the same machine as the Amiga 2000, but with a different base configuration. The CPU has been upgraded via an accelerator board to a Motorola 68020 running at 14.3MHz but an accelerator card was available with a Motorola 68030 running at 25MHz. The accellerator card was also sold separately as the A2620 (68020 CPU) and the A2630 (68030 CPU) to upgrade the Amiga 2000. The Amiga 2500 also came with the Motorola 68881 Floating Point Unit and the Motorola 68851 Memory Management Unit. The A2630 accellerator card came with the 68882 Floating Point Unit and a built in Memory Management Unit.
The Amiga 2500 was built on the same motherboard but using an accelerator card to upgrade the CPU, the original 68000 CPU was unused. This was not cost-effective and the machine got eventually replaced with the Amiga 3000, which had the upgraded CPU built in.
