The Turing Machine

The Turing Machine is the realisation of a theoretical computing machine, devised by Alan Turing in the 1920's 

He thought that anything could be computed so long as it was broken down into the smallest of steps, and there was no constraint on time taken or storage capacity. This machine was made to demonstrate that principal and uses an array of 32 'Cells' and then a head that can move back and forth, reading the cells and changing the value if necessary. 

The machine is 1.5m long, and made of oak and steel - and used in conjunction with the programmer, where the instructions and initial states are set.
The whole project, design and construction of both the machine and the programmer took just over 30 months!
