In 1946, Jan Rajchman developed the first storage device capable of storing 256 bits of data. It was a vacuum tube and it used electrostatic charges to store digital data.
It was originally designed to be used on an IAS machine, the first electronic computer to be built at the Institute for Advanced Study (IAS) in Princeton. However, the IAS machine needed more storage capabilities. Hence, the selectron tube was replaced.
Despite this, a US Air Force contract led to the continued development of the Selectron Tube. A new IAS machine used by the air force needed 80 Selectron tubes to provide 512 40-bit words of main memory.
By the 1950s, the Selectron tubes were obsolete since most computing companies preferred to use magnetic tapes for the storage devices. A similar storage device, the Wiliams tube, was also deemed obsolete when magnetic tapes started production.
Dive in and geek out on the Selectron tubes. Here’s an article with great pictures of the Selectron tubes. Need a quick explainer on the history of storage devices? Here’s a video that details everything from punch cards to SD cards.
