Excerpt from The PC Pioneers
Gordon Bell was recruited from MIT’s Speech Computation Laboratory to design the input/output for the PDP-1.
In 1972 Bell described his ‘Law of Computer Classes’. In essence he suggested that the increase in capability and decrease in price would mean that every decade computing would evolve a new class of computer. And this proved to be the case
- mainframes in the ‘50s and ‘60s
- minicomputers in the ‘60s and ‘70s
- networked workstations and PCs in the ‘80s
- web-server browser PCs in the ‘90s
- portable hand-held PCs in the mid ‘90s
- web services and cellphone PCs in the 2000s
- for the 2010s the new class was forecast to be home and body networks.
