- A600.
- They never made a upgrade for Paula
- No chunky modes in AGA. Bitplanes are nice if you are playng with up to 64 colors. A 7 bit mode is nonsense and 8 bit modes are better handled in bytes than bits
- No built in support for MMU. Check on the eternal "memory protection" discussions that we always find here
- Lack of a Memory slot for the A1200. By the time it hit the market a RAM expansion board was nonsense
