The PDP-14 was designed to process Boolean equations, usually expressed as “ladder diagrams” and as such had a programmable read-only program memory. Programs were developed using a PDP-8 then tested using a direct connection to the PDP-14. The PDP-14 was put into a check out mode where instructions were provided by the PDP-8.
Ford's internal code name for the TLCS-12 microprocessor was "PM-11" or "Poor Man's 11" implying it was a stripped down version of the, then popular, Digital Equipment Corporation PDP-11 computer. A PDP-11 was used in a vehicle in the first half of the 1970s for "proof of concept".

PDP-1 PDP-6 PDP-7 PDP-8/e PDP-11/40 PDP-12 PDP-15 (partial) PDP-15 graphics terminal with light pen and digitizing tablet. Programmed Data Processor (PDP), referred to by some customers, media and authors as "Programmable Data Processor," [1] [2] [3] is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.
The J-11 is a microprocessor chip set that implements the PDP-11 instruction set architecture (ISA) jointly developed by Digital Equipment Corporation and Intersil. It was a high-end chip set designed to integrate the performance and features of the PDP-11/70 onto a handful of chips. It was used in the PDP-11/73, PDP-11/83 and Professional 380.
An open PDP-8/E with its logic modules behind the front panel and one dual TU56 DECtape drive at the top A "Straight-8" running at the Stuttgart Computer Museum. The earliest PDP-8 model, informally known as a "Straight-8", was introduced on 22 March 1965 priced at $18,500 [3] (equivalent to about $178,900 in 2023 [4]).
The 11/34 supports up to 256 kB of Unibus memory. The PDP–11/34a (1978) [15] supports a fast floating-point option, and the 11/34c (same year) supported a cache memory option. PDP–11/60 – 1977. [15] A PDP–11 with user-writable microcontrol store; this was designed by another team led by Jim O'Loughlin. PDP–11/44 – 1979. [15]
In digital electronics, the power–delay product (PDP) is a figure of merit correlated with the energy efficiency of a logic gate or logic family. [1] Also known as switching energy , it is the product of power consumption P (averaged over a switching event) times the input–output delay or duration of the switching event D . [ 1 ]
