Building a Lego Supercomputer - The Cray-1 - Part 2

 If there was one site that inspired me whilst I was thinking about building a Lego model of the Cray-1 Supercomputer it was this one

The detailed diagrams and photos were invaluable when I was looking at how best to represent a Cray-1 in Lego.  Some of the images, from the website show the schematic diagrams for the Cray-1, seen below

These diagrams would prove invaluable when I was trying to work out the best angles for rotating each "Cray-1 Lego Unit" (the tower and seat) - And as this image below shows - it's very easy to get the angle of rotation wrong for each "Cray-1 Lego Unit" and end up creating some kind of Cray-1 auditorium!
