62295 LEO I Engineering Console (1955)


Description of Photograph

Digital copy of a photograph of the LEO I engineering console, or control desk, taken from the central aisle between the racks.

This image appears in the interactive plan for our Virtual LEO I installation, p108.

 

Research comments: The engineers' console shown in this photograph is fully populated in comparison with earlier photographs. The development of the first LEO was very much a case of trial and error, so the team's ideas of what was needed on the control panel changed over time. By the time this photo was taken in 1955, the second LEO computer was under development so there was no further major development of LEO I beyond refinements to ensure continued smooth running of the computer.

The cabinets to the left and right of the console contain racks of valves and the doors were blue (the precise shade of blue is often referred to 'Reckitt's blue after the laundry brightening product) . Much of the computer's wiring ran underneath the raised wooden floor. It looks there might be an access panel in the floor beneath the console. (LM)
