I was contacted earlier this week about a project to recover information off of an old Cray-1 supercomputer hard drive. Unlike, say, trying to get your old floppies to read or pulling an old mix tape off of a cassette, with something as old as a Cray-1 (a computer once called the “World’s Most Expensive Love Seat“), you don’t even have a place to really plug it in: functioning Cray-1 machines are rare as you can get, and even if you were to get the hard drives spinning up and read off of – where would you get the data off the Cray?
Researcher Chris Fenton has a thing about Cray supercomputers – he built a tiny homebrew version of one that used emulation to allow you to experience some aspect of Crays, from his desktop. So when he found himself with a 80 Megabyte CDC 9877 disk pack, which was quite a lot for the early 1970s, it wasn’t just a matter of hooking it up to USB. (Actually, we have a brochure for the behemoth you would put this disk pack into to read it.) Here’s what a nearly-the-same CDC 9987 looks like…
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.

Its huge! Looks like a kitchen appliance
I started my mass spec years at HP while their upmost driving computers where HP1000 running RTE operating system. At this time, these computers where using HP7906 disk drives, as big as a washing machine, containing a fixed 10 Mb disk and a removable 10 Mb disk as bigg as an XXXL pizza!
I also remember the threats of the service engineers who were maintaining these disks. You could see the drops of sweat on their face before resuming the power on the disk drives. And their were shaking like hell during the final tests.
These were good times anyway!
