PeterH, I am not super familiar with the Atari hardware so I may be looking at the wrong document, but what I found here suggests the Atari used an LFSR, which as I understand it is not ‘first class’ in the context of cryptography, where it’s important that a determined adversary doing statistical analysis not be able to figure out the stream. You need a real entropy source for the seed and a cryptographically secure RNG algorithm.
