PDP-1 SerialNumbers

This document is a detailed serial number list for PDP-1 computers, updated as of 20060819. It tracks over 50 individual PDP-1 systems, specifying their type (e.g., PDP-1C, PDP-1D, ADX), original installation location (WHERE), date of information, source of information (e.g., CHM aperture cards, DEC Photo Archive), and associated peripherals.

Many entries indicate missing or unknown dates and sources. The document notes that some unknown systems might correspond to missing ADX units (ADX-1 through ADX-8). Specific entries include notes about unique sales (e.g., PDP-1s replacing a PDP-3) or configurations (e.g., Q-32 front-end).

Additionally, the document provides a separate list of organizations and institutions known to have owned PDP-1s based on DECUS submissions, along with the dates of these submissions or acquisitions.
