CRAY-1 Hardware Reference Manual

Cray-1-Hrm-204

CRAY-1 Hardware Reference Manual… you may have misplaced the manual, here’s a copy…

The CRAY-1 Computer System is a powerful general-purpose computer capable of extremely high processing rates. These rates are achieved by combining scalar and vector capabilities into a single central processor which is joined to a large, fast, bi-polar memory. Vector processing by performing iterative operations on sets of ordered data provide results at rates greatly exceeding result rates of conventional scalar processing. Scalar operations complement the vector capability by providing solutions to problems not readily adapted to vector techniques.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Very, very cool. I’ve been browsing through the other manuals on the site, and there are a lot of interesting, arcane, and obsolete manuals to keep me awake at night, thereby supporting my insomnia.

    Many years ago, I worked for a pioneering Hollywood computer graphics special effects company (Digital Productions) that used a Cray-1 for rendering. This was before the advent of graphics workstations and personal computers, in the stone age of CGI.

    What you can’t tell from that drawing is that the bench around the base of the computer, which housed all the cooling systems and tubes used to keep the massive vertical arrays of processors and memory from overheating, was covered in leatherette cushions.

    It made a fine place to curl up and catch a few winks while babysitting those long, long overnight rendering jobs.
