One definition from 1970 required a minicomputer to cost less than US$25,000. [3] In contrast, regular mainframes could cost more than US$1,000,000. [2] By the end of the 1960s, mainframe computers and minicomputers were present in many academic research institutions and large companies such as Bell Labs.
As of 2010, while mainframe technology represented less than 3% of IBM's revenues, it "continue[d] to play an outsized role in Big Blue's results". [ 28 ] IBM has continued to launch new generations of mainframes: the IBM z13 in 2015, [ 29 ] the z14 in 2017, [ 30 ] [ 31 ] the z15 in 2019, [ 32 ] and the z16 in 2022, the latter featuring among ...
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 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 ...
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]
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.
A review of the goal showed South Africa’s Percy Tau had been fouled inside the penalty area at the start of the move and the score went from 2-0 to Nigeria to 1-1 when Mokoena made no mistake ...
The Cyber 18 is a 16-bit minicomputer which was a successor to the CDC 1700 minicomputer. It was mostly used in real-time environments. One noteworthy application is as the basis of the 2550—a communications processor used by CDC 6000 series and Cyber 70/Cyber 170 mainframes. The 2550 was a product of CDC's Communications Systems Division, in ...
