The Architecture of IBM's Early Computers
Charles J. Bashe, W. Buchholz, G. V. Hawkins, J. J. Ingram, N Rochester · IBM Journal of Research and Development · 1981
Most of the early computers made by IBM for commercial production are briefly described with an emphasis on architecture and performance. The description covers a period of fifteen years, starting with the design of an experimental machine in 1949 and extending to, but not including, the announcement in 1964 of System/360.
