The appearance of even lower-priced scientific workstations (e.g., Dana Computer/Ardent Computer/Stellar Computer (the merger of these companies)) based on microprocessors with high performance floating point units (FPUs) during the 1990s (such as the MIPS R8000, IBM POWER2), and Weitek eroded the demand for this class of computer.
A superminicomputer (Interdata 7/32) preserved in a museum. A superminicomputer, colloquially supermini, is a high-end minicomputer. [1] The term is used to distinguish the emerging 32-bit architecture midrange computers introduced in the mid to late 1970s from the classical 16-bit systems that preceded them.
Since the rise of the personal computer in the 1980s, IBM and other vendors have created PC-based IBM mainframe-compatible systems which are compatible with the larger IBM mainframe computers. For a period of time PC-based mainframe-compatible systems had a lower price and did not require as much electricity or floor space.
This list of computer size categories attempts to list commonly used categories of computer by the physical size of the device and its chassis or case, in descending order of size. One generation's "supercomputer" is the next generation's "mainframe", and a "PDA" does not have the same set of functions as a "laptop", but the list still has ...
The "Micro Channel 370" Models 010, 012, 014 (later 110, 112, 114) ES/9371 introduced in 1990 used the Micro Channel bus and a 386 CPU for input/output (I/O) processing. Additionally, a dual-processor model was offered, providing a second 386 CPU for DOS and OS/2 applications, implementing a high-speed link between the processors.

The term supercomputer itself is rather fluid, and the speed of today's supercomputers tends to become typical of tomorrow's ordinary computer. Supercomputer processing speeds are measured in floating-point operations per second, or FLOPS. An example of a floating-point operation is the calculation of mathematical equations in real numbers.
From 1965, Gene Amdahl had been working at IBM on the IBM Advanced Computer Systems project (ACS), which intended to introduce what would be the world's fastest computer. . During a shake-up of the project in early 1968, Amdahl suggested the company to abandon the ACS-1 concept and instead use the techniques and circuit designs to build a System/360 compatible de
