The 'Big Hex Machine' is a giant, yet simple, 16-bit computer specifically designed to explain how a computer works. Its instruction set requires a very small compiler, but it is powerful enough to implement useful programs.
The giant machine, based in the Merchant Venturers School of Engineering, measures over eight square meters. It is built out of over 100 specially designed four-bit circuit boards, which enables students to be taught about fundamental principles of computer architecture from just a few basic components.
It was designed, and built, by students and staff at the University of Bristol's Computer Science Department.
