A couple of years back my other half bought an Atari 7800 console for me which I really enjoy using, firstly for the 7800 games and also for the 2600 backward compatibility. I know this is a computer site rather than console one but I was curious what 8bit Atari computer the 7800 is closest to in terms of architecture. I know that originally the 7800 was intended to be fully expandable to a computer but this idea was scrapped when Jack Tramiel took over at the company. A few years later Atari made the XEGS which was a Computer/Console hybrid. It got me thinking about what could have been for the 7800.
