I just finished building a frame for some resurrected LED panels from a decommissioned super computer. The computer was a CM-5 by Thinking Machines. It has been used at the College of Oceanography and Atmospheric Science at Oregon State for a fairly long while. A few weeks ago, its time came, and we surplussed it. I was able to get the light panels and built a frame for them at my house. This post describes a little about the process and includes some trivia about the CM-5 and the panels themselves.
What an awesome part of history!
