The Baby was built to test a new memory technology developed by Williams and Kilburn -- soon known as the Williams Tube – which was the first high-speed electronic random access memory for computers. ]]> 2021-09-30 15:25:55 UTC https://padlet.com/27pandyar/47zx6yawmzg5uc3d/wish/1781784199 27pandyar https://padlet.com/27pandyar/47zx6yawmzg5uc3d/wish/1781815358 While many early digital computers were based on similar designs, such as the IAS and its copies, others are unique designs, like the CSIRAC.
