Chris Fenton is cloning a cycle-accurate Cray-1A. In 1/10 scale. Awesome.
I was especially smitten with the Cray 1 Hardware Manual’s Computation Section architecture diagram:
I love the hand-drawn draftsman’s lines, use of pseudo-3D projection as a grouping construct and its rectangular dimensioning to graphically depict register capacities.
I’ve created similar diagrams, but this one makes mine feel chart-junky.
