Well one could certainly build a basic computer from the 7400 IC series if committed, as shown here:

Actually most of the popular minicomputers of the 70s (DEC, HP, DG, etc) were built with lots of pretty basic gates, FFs and registers. The most complex chips used were typically 74(X)181s for the ALU and LSI UART chip for serial communications. Layout was usually pretty straight forward for all the data paths. It was the instruction decode area that was usually a mess
