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 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.
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 ...
Midrange computers, or midrange systems, were a class of computer systems that fell in between mainframe computers and microcomputers. [1] [failed verification]This class of machine emerged in the 1960s, with models from Digital Equipment Corporation (PDP lines), Data General (), and Hewlett-Packard (HP 2100 and HP 3000) widely used in science and research as well as for business - and ...
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 ...
Nigeria vs Angola - LIVE Goal - Lookman scores his third in two knockout games to put Nigeria ahead on 41’ (1-0) Post - Zini latches onto through pass and beats the keeper but hits the post on ...
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 ...
