This day 60 years ago, the first modern computer, nicknamed the Manchester “Baby” was switched on to run it’s first successful program. Baby was the first computer to store information digitally, using a Cathode Ray Tube (or CRT), and is the predecessor for how we store information in modern RAM chips.

The invention and concepts 60 years ago were monumental after people realised for the computer to be of any real use, the information would have to be stored permanently and electrically by the machine. Although the data was added by hand, the Baby would constantly read and refresh the bits on the CRT, it’s memory, electronically to keep them from decaying, and is a concept still in use by RAM today. By the time it was revealed this method was capable of storing 4096 bits.

The first program was run on the Baby, this day 60 years ago. One of the inventors, F.C. Williams, spoke of the monumental occasion, “A program was laboriously inserted and the start switch pressed. Immediately the spots on the display tube entered a mad dance. In early trials it was a dance of death leading to no useful result, and what was even worse, without yielding any clue as to what was wrong. But one day it stopped, and there, shining brightly in the expected place, was the expected answer. It was a moment to remember. This was in June 1948, and nothing was ever the same again.”
