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.
