How successful?

The Amiga range, particularly the later 500, 600 and 1200 models, were amongst the most popular home computers well into the 1990s. Several million were sold.
Commodore had a $25 million advertising budget for 1985.


The Amiga's chief architect was Jay Miner, who had previously worked for Atari on the custom chipsets in the 400 and 800 series.
When the Amiga company ran out of money while designing their new machine they were given a loan by Atari, who had intended to incorporate Amiga technology into a new Atari range.
In the event Commodore outbid Atari for the Amiga technology so Atari developed the ST range independently of Amiga, and the Amiga design was bought by Commodore.

The original Amiga 1000 impressed the industry with its capabilities but was a little too expensive for the home market. In April 1987 the Amiga 500 was launched, with 512 KB of RAM, expandable up to 9 megabytes, in a one-box console style design, priced at £600.

The A500 type sold very well but in early 1992 Commodore replaced it with the A600. This achieved a very compact size by doing away with the numeric keypad and was intended as a low cost model to be used mainly as a games console.
Amiga 600

It seems though that many customers missed the number keys and in late 1992 the A1200 was produced, essentially the same as the A600 but with the numeric pad reinstated and priced at £400.
