Fingers Crossed for 2021 ...

2020 was the worst! COVID kept the museum closed for much of the year and a mains water pipe bursting causing a flood kept us closed for the rest. 
We're hoping to re-open in the next few months ... fingers crossed! Read More >>>

61853 View across the LEO I racks towards the power supply units (1950)

Description of Photograph

Digital copy of a photograph across the LEO I 'calculator room' at Cadby Hall, early in the installation phase.

Caption:  'Computer & Co-Ordinator Racks'

This image appears in the interactive plan for our Virtual LEO I installation, p63.

Research comments: This photograph shows some of LEO I's racks; the racks contained the almost 6,000 valves the machine was eventually made up of. At this point in time, quite early in the machine's construction, some racks are still unoccupied. In the background, LEO's power supply is being developed. (LM)
