Page "Atari Lynx" Paragraph 11

As with the actual console units, the game cartridges themselves evolved over the first year of the console's release.

The first generation of cartridges were flat, and were designed to be stackable for ease of storage.

However, this design proved to be very difficult to remove from the console and was replaced by a second design.

This style, called " tabbed " or " ridged ", used the same basic design as the original cartridges with the addition of two small tabs on the cartridge's underside to aid in removal.

The original flat style cartridges could be stacked on top of the newer cartridges, but the newer cartridges could not be easily stacked on each other, nor were they stored easily.

Thus a third style, the " curved lip " style was produced, and all official and third-party cartridges during the console's lifespan were released ( or re-released ) using this style.
