From https://cray-cyber.org/old/systems/E10kborn.php How the Sun Enterprise 10000 was born A group of engineers in San Diego left their jobs at well established corporations (especially a large number of former NCR employees) to form their own company. They set out to build massively parallel computers with Sparc processors. The market they were targetting has traditionally been

Cray Stories During the 25 years that I worked for Cray I was fortunate enough to meet many interesting people and hear many stories and urban legends about Seymour Cray, the company as well as interesting events that happened in the field. In some cases I even got to hear the story behind the story.

From about 1987 to 1997, it was traditional that Cray Research would ship a customer system book showing images from the factory of how the system was built. Included in the book, were pictures of the staff and machines that built the customers machine. A couple of examples of the system book have been captured
