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.
TI-990 programmers panel. The TI-990 was a series of 16-bit minicomputers sold by Texas Instruments (TI) in the 1970s and 1980s. The TI-990 was a replacement for TI's earlier minicomputer systems, the TI-960 and the TI-980.
The VAX-11/782, code-named "Atlas", [10] is a dual-processor VAX-11/780 introduced in 1982. Both processors share the same MA780 multiport memory bus and the system operates asymmetrically, with the primary CPU performing all I/O operations and process scheduling with the second, attached processor only used for additional computationally-intensive work.
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.
A mainframe computer, informally called a mainframe or big iron, [1] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
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.
