Amiga 500 Amiga 500+ Amiga 1000 Amiga 1200 Amiga 1500 Amiga 2000 Amiga 3000 Amiga 4000 Commodore created the A500+ for a couple of reasons. The first was cost reduction; minor changes were made to the motherboard to make it cheaper to produce. It was also so that Commodore could introduce the new version of the Amiga Operating system, 2.04.
The plus was released almost in secret; many users didn't realise they weren't purchasing anything other than a "normal" A500. Due to the new Kickstart, quite a few popular games failed to work on the A500+, and a lot of people took them back to dealers demanding an original Kickstart 1.3 A500.
