Imagine a computer like a PDP-11 but with more than 3 billion SP4T switches. The switches are various combinations of 'magic' and 'more magic'

the authors of the code are dead, there are no comments except for old code, and sometimes the comments run anyway

and it's wet

this is biology.

@NanoRaptor and every once in a while almost every PDP-11 sets another 3B toggles nearly identically to itself, just to see whether some variation will be a better fit for the server room.
