Can be had cheap nowadays, and I recommend it.
The GameBoy Advance was also backward compatible and could play many GB and GB Color games, but it was much much more powerful than the original GameBoy. The GB and GB Color could not play ANY GB Advance games. It was a significant departure in hardware, and therefore classified as a separate system.
Here I am, commenting on a six-year-old comment... I really must have better things to do
Also, which Atari is that? Is it all Atari systems lumped together? I think the 2600 sold by far the best, but there was also the 7800, 5200, XE, and several systems before the 2600 that were not as popular.
Still, I never knew anyone who had either Turbo system. I played it only when I went to Toys R Us.
If the book fails to mention this very important aspect of how things unfolded, then it is a poor representation indeed. From all the reviews I read it seems like it's really kind of just an ego piece about Tom Kalinske at SOA Marketing. If an author relies too much on testimony from one person and those close to him he's going to end up with an incomplete picture.
It was getting hard, but in the end I remembered TurboGrafx-16 as one if my random guesses.
