HARVEST

The HARVEST computer (a.k.a. IBM 7950) was a one-of-a-kind cryptanalytic machine designed and built by IBM and the NSA in the late 1950s and early 1960s. In 2010, the NSA declassified a number of documents about HARVEST, revealing more of the machine's design and the planning process that led to it. Here, you'll find some of these documents, as well as articles about the history and architecture of HARVEST.

Technical and Historical Articles

These articles discuss some architectural, logistical, or historical aspects of HARVEST I found interesting.
