I'm still astonished at the constraints those guys had to suffer:
PDP-7 Unix provided a multitasking environment by dividing the 8K
words of memory into two halves. The lower half of memory was
reserved for the kernel. The upper half of memory was set aside for
the currently running process.
But you try and tell the young people today that... and they won't believe
you.
