It often strikes me that the opening line of Neuromancer, which is something like "The sky was the color of a TV tuned to a dead channel" must be losing its meaning to newer readers.
Just the other day I was reading some early Neal Stephenson, and it made reference to 32-bit personal computers as being on the cutting edge. I guess you could read it as a period piece. Similarly, a novel about a computer that was written in the 1950s describes a machine a city block on a side, cooled by Niagra falls, with 1000 bits of storage, that somehow still forms the pillar of a surveillance society.
Novel writers are not the best predictors of technology, it would appear. That's okay.
It was Gaiman in his series introduction to the Penguin Galaxy [1] reprint in hardcover of Neuromancer, Dune, 2001: A Space Odyssey, The Once and Future King, The Left Hand of Darkness, and Stranger in a Strange Land.

Did anybody really write that? The first electronic stored-program computer, the Manchester Baby (1948), had 1024 bits of storage. Even assuming no miniaturization, just scaling up contemporary computers would have gotten you more than 1000 bits.
(It might have been a megabit, but it sure wasn't much compared to what you need in order to run a computerized dystopia...).

Terry Pratchett realized this... I can't find the quote now, but one of his books (Good Omens?) starts "The sky was the perfect blue of a television tuned to a dead channel..." (can't recall if "over the port" is in there).
Edit: I'm sure this is discussed back and forth ad nauseam at HBO...
