In 1953, when a patent was issued to Syd Darlington, the general attitude at Bell Labs was that Syd was right and that this would happen some day but that it had to wait until we had a better way to make transis tors. The alloy junction was in deed a better way and when it became a reality, Harwick Johnson at RCA Princeton took the concept even further and built a phase shift oscillator. Again, the general response was, 'Well, this is a lot better but it still isn't right.' Then Kilby took the concept of the dif fused base mesa transistor even further. I remember my reaction was, 'Well, it's closer, but it still won't fly.' Then came Bob Noyce's suggestion using the planar pro cess and we all ran very fast to bring that one process to reality." The exhibition will be changed to reflect this evolutionary development. Our display of Super Computers is especially dynamic.
