This is widely known as the shortest-lived Amiga ever, lasting only 6 months until it was phased out by the A600. This was yet another of Commodores secrets with many people opening their Amigas at Christmas expecting to find a A500 only to find something much better. It looked physically similar to the A500, but updated it with 1mb of ram, Enhanced Chip Set (ECS) and Workbench 2.0 which turned the horrible blue interface of workbench 1.3 into a much more lovely grey and blue.
It also allowed the user to see files that did not have icons without resorting to the CLI and put among other things the FastFileSystem into ROM (Kickstart) allowing you to boot from FFS disks containing 880k of data.
