A Bell Labs 'Transistor History' Paperweight (1967)


The "Brains" inside a computer that enables it to rapidly process data have quickly evolved over the years - From using vacuum tubes in the 1940s, to transistors in the 1950s, Hybrid Circuits in the 1960's, integrated circuits in the 1970s, and Very Large Scale Integrated circuits (VLSI) in the 1980s.
