ANNOUNCING THE DIGITAL EQUIPMENT CORP. PDP-11 PROCESSOR

PDP-11 is Digital's answer to the demand for a modular system for
real-time data acquisition, analysis and control.  PDP-11 systems can
handle a wide variety of real-time control applications -- each system
being individually tailored from a comprehensive array of modular
building blocks.  Digital is unique among manufacturers of small-scale
computers in its ability to provide not only fast and efficient
processing units, but also a large family of its own compatible I/O
devices including A/D and D/A converters, magnetic tape, disk storage,
paper tape, and displays, as well as a wide range of general-purpose
modules.  This capability offers the user a new, more efficient
approach to real-time systems.

The PDP-11 is available in two versions designated as PDP-11/10 and
PDP-11/20.  The PDP-11/10 contains a KA11 processor, 1,024 words of
16-bit read-only memory, and 256 16-bit words of read-write memory.
The basic PDP-11/20 contains a KA11 processor and 4,096 words of 16-bit
read-write core memory, a programmer's console, and an ASR-33
Teletype.  Both versions can be similarly expanded with either
read-write or read-only memory and peripheral devices.

[The fact that the amazing PDP-11 was new and untested presumably led
Ken Thompson to implement the first UNIX (tm) system in the B language
on the tried-and-trusted PDP-7 one year later.  What did one run on a
"basic configuration" PDP-11/10 or 11/20?]
