The Atari 7800+ is a trip down the retro rabbit hole

It’s a bit easier than you might expect. Sales were pretty lousy but despite there only being 59 games released they sure manufactured a whole lot of them. In my experience every used game store with 4-6 linear shelf feet of stacked loose 2600 carts will probably have a dozen or so 7800 carts somewhere in the same vicinity. It’s a pretty easy catalogue to collect the whole set of if you don’t mind shelling out some real cash for the very small number of truely rare carts.
