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.
The project consisted of 4 modules: an economic simulator, custom software to check factory performance, an operations room, and a national network of telex machines that were linked to one mainframe computer. [2] Project Cybersyn was based on viable system model theory approach to organizational design and featured innovative technology for ...
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 CDC Cyber 170 Computer room, 1986 A CDC Cyber 70/74 A CDC Cyber 70/74 console. The CDC Cyber range of mainframe-class supercomputers were the primary products of Control Data Corporation (CDC) during the 1970s and 1980s. In their day, they were the computer architecture of choice for scientific and mathematically intensive computing.
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 ...
6000-series systems were said to be "memory oriented" — a system controller in each memory module arbitrated requests from other system components (processors, etc.). Memory modules contained 128 K words of 1.2 μs 36-bit words ; a system could support one or two memory modules for a maximum of 256 K words (1 MB of 9-bit bytes).
These systems ran a variety of clone operating systems - DEMOS (based on BSD Unix), MOS VP (based on VAX/VMS) or MOS VP RV (based on VAXELN). [ 32 ] The NCI-2780 Super-mini, also sold as Taiji-2780, is a clone of the VAX-11/780 developed by North China Institute of Computing Technology in Beijing.
