I am remember a product that was advertised in the
old "Amazing Amiga" and "Amiga World" magazine way
back in the day that advertised complete Atari
compatibility. I don't remember the name but it was
a hardware and software solution. Other than that, I
have never seen one or heard of anyone that used it.
I will look back in my old magazines and scan the ad
if I find it.
