The Evolution of the DECsystem-10

C. Gordon Bell, Alan Kotok, Thomas N. Hastings, Richard Hill 1978 View original ↗

TL;DR — DEC’s own retrospective on why the PDP-10 lasted — a clean architecture and an address space big enough to be useful.

DEC’s engineers on their own machine. The verdict is in the first line: “We believe the key to the 10’s longevity is its basically simple, clean structure with adequately large (one Mbyte) address space that allows users to get work done.”

The PDP-10 shaped a generation — timesharing, the early ARPANET, the MIT AI Lab, and the culture that came out of them. This is the designers’ account of which decisions actually carried the weight, written while it was still commercially alive.
