The 5000 series Laboratory Modules and 6000 series Systems Modules go on the market.

DIGITAL's 5000 and 6000 series modules were made possible by the arrival of a new series of transistors. This second generation of modules ran at 10 MHz, compared to the first generation modules which ran at 5 MHz.

The first DIGITAL Logic Handbook is published.

The Logic Handbook was an early project of Barbera Stephenson, the first woman hired as an engineer at DIGITAL. The Logic Handbook was the first in a long series of handbooks that worked both as textbooks and promotional tools. DIGITAL sent them to every customer and handed them out at trade shows.

From a technical bulletin on the PDP-1, dated March 1960: "...a compact, solid state general purpose computer with an internal instruction execution rate of 100,000 to 200,000 operations per second. PDP-1 is a single address, single construction, stored program machine with a word length of 18-bits operating in parallel on 1's complement binary numbers."
