The PDP-11 was, and is, an extremely successful and influential family of machines which has spanned over two decades from the early 1970s through the mid 1990s. This note is an attempt to gather some of the knowledge on this family and present it for the benefit of those who are enthusiasts, curious, or downright confused as to what the -11 was and is, and how it related and still relates to its world.

The information presented is compiled from the memory and notebooks of both myself and a number of people who have filled in the many gaps in my memory or set me straight on certain details.
