Building a Lego Supercomputer - The Cray-1 - Part 5

The image below shows an early redesign featuring a new seat height and an "additional" tower between the two existing towers - to create more of the cylindrical outer shape of the Cray-1 towers 

With the revised hinge construction under the seat to place the base of the "middle" tower

It was this basic design would become the basis of the final model for each of the "Cray-1 Lego Units" - the base and now the two towers - that would be used in the Lego Cray-1 Supercomputer - in theory duplicating each of the "Cray-1 Lego Units" should create the the classic cylindrical design.
