Typical ScreenShot (Workbench 1.2/1.3)

The Commodore Amiga 500 is the low-end successor of the Amiga 1000 and and the predecessor of the Amiga 1200.
It was the main competitor of the Atari 520 STf (there was a great "war" between the owners of these two computers).

It uses a special system for its RAM configuration: 512 KB of Chip RAM which can be accessed by the Paula and Denise custom chips (sound & I/O and video, respectively) and Fast RAM which can be accessed only by the CPU.

An extension card can be connected to the 68000 bus (thanks to the external connector) and offered a battery-backed clock (this Amiga model doesn't come with one). The 68000 bus has two connectors: an external and an internal one.

The Amiga 500 was followed with the Amiga 500+. The Amiga 500+ has the same characteristics as the Amiga 500 exept it has 1MB of Chip RAM and uses the AmigaOS 2.04, this version of Amiga OS needs a 512 KB ROM.
