I find the whole period amazing. Consider that the 709 was introduced in mid 1958. It's only 6 years to the S/360. It seems that when transistor manufacture matured enough, the floodgates really opened. After 1958, nobody but developing or Warsaw pact countries even considered vacuum tube computing. --Chuck
