The IBM 7094 was IBM's last commercial scientific mainframe (built at a time when computers for scientific and business computing used separate instruction sets).
It had about 1.4-2.4 time the computer power of its predecessor, the IBM 7090. It was upwardly compatible with the 7090, but did have extra index registers (going from three to seven), and hardware double-precision floating point support.
It appeared in two models: the original 7094 (sometimes known as the 7094 I); and the 7094 II, announced in May, 1963, with the first installation in April, 1964.
The latter had about twice the speed of the original; due in part to the introduction of pipeline techniques (pioneered by the IBM STRETCH), but also a slightly faster clock.
Total production amounted to 130 7094 I's, and 125 7094 II's.
