Clive England and David Laufer have presented their slides for their talk about the Cray-2 computer earlier this year. Full of facts on this amazing machine.
Four best features of the Cray-2
• Density of electronics, it’s a very small machine compared to contemporaries.
• Speed of processor using a 4 nanosecond clock – way ahead of its time
• Size of main memory – up to 30 times size of Cray-1 & XMP – could run problems that would bog down on other systems. Very good at CFD codes.
• First Cray with direct interactive access for users alongside batch work. Due to using Unix as base for Unicos operating system
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
