The IBM 303X was a line of mainframe computers, the first model of which, the IBM 3033 Processor, was introduced March 25, 1977.
Two additional processors, the 3031 and the 3032 were announced October 6, 1977.
Each of the three included, as a standard feature, a Dual-display console, the newly announced IBM 3036. Furthermore, the systems consumed less than half the floor space of a System/370 with an equal amount of computer memory and an identical number of channels because "the channels are physically integrated within the processor mainframe."
All three 303X systems were withdrawn February 5, 1985.
Beginning in 1977, IBM began to introduce new systems, using the following descriptions:
At this time, other companies were competing with IBM and producing IBM-compatible systems. A Winter 1975 Computer Weekly article began "In the wake of the Amdahl challenge, which has already hit seven major 360 and 370 installations in the US and Canada, IBM has announced ..."
By the late 1970s and early 1980s, patented technology allowed Amdahl IBM-compatible mainframes of this era to be completely air-cooled, unlike IBM systems that required chilled water and its supporting infrastructure.The 8 largest of the 18 models of the ES/9000 systems introduced in 1990 were water-cooled; the other ten were air-cooled.
By comparison, the October 17, 1977 Computerworld reported that Itel's "air-cooled AS/6" was announced "within six hours of the IBM announcement" and due to ship "the same time deliveries of the IBM 3032 are slated to begin."
IBM considered it noteworthy that "processor storage ... is four-way interleaved" resulting in "a significantly faster data rate than...
The 3031 had 15 models, the 3032 had 4 Models, and the 3033 had 29 Models.
After itemizing which other Operating systems support the 3031, IBM specifically added "In addition, the 3031 is supported by DOS/VS."
The March 25, 1977 announcement of the 3033 also introduced "MVS/System Extensions (MVS/SE) and VM/System Extensions (VM/SE)."
