I always assumed cable modems run linux (but its not clear from this post if it actually does run linux on its main cpu). Most, if not all, PON equipment now runs linux but modems were a different type of thing back then. DOCSIS modems were buggy, ran really hot and were really just a bad experience overall if you lived in a crowded area (because more contention ratio meant more problems with signal). The worse the signal, the hotter these ran (I am assuming more noise filtering was needed ? I might be wrong). If someone can actually get these to do something good that would be great. But in general I am glad this is one piece of tech that has stopped existing in my area and everyone has moved to fiber.
