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 VAX 8600 was a successful model and at the time was the best selling high-end VAX. It was succeeded by the VAX 8800 family in 1987. The VAX 8600 has a CPU with an 80 ns cycle time (12.5 MHz) implemented with emitter coupled logic (ECL) macrocell arrays (MCAs).
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.
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.
The first complete systems were shipped to dealers in the autumn of 1974. The basic unit, model 720 with an 800 kHz 8008, [6] 2 KB RAM [16] and no cassette drive sold for $4,950 Canadian (at the time the dollar was about equal to the US dollar). [17] The fully equipped model 782 with 8 KB and two drives was $9,800, and was the only model that ...
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 ...
Super Micro Computer (NASDAQ: SMCI) has been one of the key players in the artificial intelligence (AI) boom, working hand in hand with top chip designers, like Nvidia, to build out infrastructure.
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.
