Soon after his transfer to AERE Harwell in 1948, he supervised the production of the Harwell Dekatron Computer, working with fellow designers Dick Barnes and Gurney Thomas.

The machine was decimal and initially had twenty eight-digit dekatron registers for internal storage, which was increased to 40 which appeared to be enough for nearly all calculations.

The Harwell computer ( Dekatron ), now at the National Museum of Computing at Bletchley, was built in 1949 and is believed to be the oldest working digital computer in the world.

The dekatron was used for computing, calculating, and frequency-dividing purposes because one complete revolution of the neon dot in a dekatron meant 10 pulses on the guide electrode ( s ).

Later, with the development of electronic indicators, which started with the introduction of the Dekatron readout tube in the 1950s, and culminating in the modern digital indicator, totalised readings came to be directly indicated in decimal notation.
