I sumbled over this wonderfull items of my roots in computing. With the C64 I learned coding (I had no medium to save anything, so every time I started it, I had to built something myself first)
And the Cray was a dream back then. Cray not only made the supercomputers of that time, they made them stylish too. There was one with a watercooled system. They made a well out of it!
