IBM subsequently announced models 120, 150, 180, 300, 500 and 600 with lower, intermediate and higher capacities; the first digit of the model number gives the number of central processors.

IBM's offering of an optional vector facility (VF) extension for the 3090 came at a time when [[Vector processing]]/Array processing suggested names like [[Cray]] and [[Control Data Corporation]] (CDC).<ref>the hyperlink on the words "Vector processing" point to an article that has only 2 mentions of IBM, one of which begins "In 2000, IBM, Toshiba and Sony collaborated."</ref><ref>The "first to market" advantage can be summarized as "In 1972, computer designer Seymour Cray left CDC and formed a new company" as noted in Getting Up to Speed: The Future of Supercomputing, 2005, {{ISBN|0309165512}}, by National Research Council, Division on Engineering and Physical Sciences, Computer Science and Telecommunications Board</ref>

The 200 and 400 were withdrawn on May 5, 1989.
