    This module is the central unit of the IBM System/360 model 30 and it contains the calculation unit, the main memory, the microprogram and the central controllers of the peripherals. It also had a read-only internal memory which stored a microprogram which was personalised by the architecture of System/360. System/360 included the default implementation of a byte as an 8-bit sequence. This central unit which housed the CPU of the system could operate with different modules.

    Also known as IBM 2030, in 1964 it was a pioneering third-generation computer. This means it was the first computer to use integrated circuits or solid state logic, subsequently simplified for manufacturing processes, while it provided a considerable increase in the capacity for calculation and features in general.
