A minicomputer, or colloquially mini, is a type of general-purpose computer mostly developed from the mid-1960s, [1] [2] built significantly smaller and sold at a much lower price than mainframe [3] and mid-size computers from IBM and its direct competitors. By 21st century-standards however, a mini is an exceptionally large machine ...
Several notable technical, economic, and political attributes characterize minisupercomputers. First, they were architecturally more diverse than prior mainframes and minicomputers in hardware and less diverse in software. Second, advances in VLSI made them less expensive (mini-price). These machines were market targeted to be cost-effective ...
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 value, as it provides a ranked categorization of devices. It also ranks some more obscure computer sizes.
Companies that sold mainframe computers began to offer machines in the same price and performance range as superminicomputers. [10] By the mid-1980s microprocessors with the hardware architecture of superminicomputers were used to produce scientific and engineering workstations. [11] The minicomputer industry then declined through the early ...
An additional 370 channel card can be added to provide mainframe-specific I/O such as 3270 local control units, 3400/3480 tape drives or 7171 protocol converters. Although a single-card product, the P/370 ran three times faster than the 7437, attaining 3.5 MIPS, on par with a low-end IBM 4381. [17]
For example, the computers behind the first Space Shuttle simulator consisted of thirty-six 32-bit minis inputting and/or outputting data to networked mainframe computers (both IBM and UNIVAC), all in real-time. The 8/32 was used in the Lunar and Planetary Laboratory, Department of Planetary Sciences at the University of Arizona for research ...
A single-frame IBM z15 mainframe. Larger capacity models can have up to four total frames. This model has blue accents, as compared with the LinuxONE III model with orange highlights. A pair of IBM mainframes. On the left is the IBM z Systems z13. On the right is the IBM LinuxONE Rockhopper. An IBM System z9 mainframe
