Since initiating the information technology industry-wide transition from bipolar to CMOS technology with the first generation of S/390® processors in 1994, IBM reached another major milestone with the introduction of the third generation in September 1996. The balanced system and cache structure and the modularity of the components of Generation 3 support a wide performance range from a uniprocessor to a high-performance multiprocessing system. Because of this modularity, Generation 4 is also based on this structure.
