The reason AAA was left to languish is simple; Commodore originally made their money in the computer industry in an era where you could make a computer and keep selling it year after year with little or no changes, like the C64.
The late 80's were a totally different market place; the PC world being flooded with clones meant that every few months something faster came along. You just couldn't compete if you kept releasing the same thing year after year.
But Commodore thought they could just follow the C64 approach; cost reduce and refine the same basic design. A500, A500+, A600.
