Amiga 500 and the external Harddisk

Amiga 500 - 04
	   
In 1987 Commodore released the A500 - a cheaper version of the A1000 -
which came in the "distinct" Commodore box. 
The basic system still used the 68000 processor, 512k ram, 
and OCS chipset but had got rid of the ZORRO slots in favour of a
DMA slot at the side of the machine. The operating system had been upgraded
to version 1.3, which included the Amiga Command Line Interface (Shell)
allowing the user more functionality. This is the machine that kicked the
entire Amiga world into focus and brought more people to the Amiga than has
been done since. It was voted "Home Computer of the Year" (36.7) in 1991
by a selection of Greek and Italian publications 

There are two different revisions of the A500 motherboard: 

Amiga 500P (American) the 'Productivity' edition features 1Mb memory
(512k Chip, 512k Fast). 

Amiga 500C (American) an improved version that incorporated the new 
Agnus chip, providing 1Mb Chip RAM (corresponds to the Amiga 2000C).

The Commodore Amiga 500 is the low-end successor of the Amiga 1000 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 offers a battery-backed clock
(the Amiga 500 doesn't have any - the 500+ does). 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.
