Three months later a fourth IBM System/370, the Model 145, was announced. Since none of them came with virtual memory, "which was to be a hallmark of the 370 line"[4] some said about these early members of the IBM System/370 family, especially about the 165 and 155, that they were not "the real 370 line."[NB 2]
