Like much of the diagnostic cartridges circulating among Atari collectors, this PAM Diagnostics was not designed for the public but for repair shops and quality control on the production line: it runs a battery of tests on the machine's memory, control ports, and video hardware, showing technical results on screen instead of any kind of entertainment. Its exact origin is poorly documented outside the technical circles that preserve this kind of material. It's worth knowing for what it is: a service tool that ended up filed alongside the games purely because of its cartridge format, not an experience meant to be played.
