As @IsaacKuo mentioned retrocomputing in his Postcards from Cutty work, in ROM based home computers since Atari ST?, I thought we could have a thread. (By SF I include Science Fiction, Speculative Fiction, and Fantasy.)
It’s possible there will be spoilers ahead.
There’s computing in old SF, there’s old computing in SF, and then there’s SF which a retrocomputist might enjoy.
For example, Diamond Age is a nice book with a sort of steampunk outlook, and mechanical (nano)-computing.
Shockwave Rider “envisaged the emergence of computer viruses”:
The Machine Stops (pdf) is a 1909 short story with dystopian centralised information management, IIRC.
Recently on mastodon, I opined:
Vernor Vinge is really good for computer-literate hard SF. Just the prologue to Fire Upon The Deep is excellent in itself. “Archaeologist programmers”! And “Programmer at war”… it’s all about info-war, and layers of ever-older software, and the risks of working with code you don’t fully understand, and the impossibility of fully understanding code which is sufficiently advanced. [I’m now well into a re-read of this book as a consequence of posting about it…]
