A 3270 Emulator is a terminal emulator that duplicates the functions of an IBM 3270 mainframe computer terminal on a computer, usually a PC or similar microcomputer . As the original 3270 series terminals were connected to the host computer through a display controller (cluster controller) [a] using coaxial cable, emulators originally required ...
Hercules (emulator) Hercules is a computer emulator allowing software written for IBM mainframe computers ( System/370, System/390, and zSeries/System z) and for plug compatible mainframes (such as Amdahl machines) to run on other types of computer hardware, notably on low-cost personal computers. Development started in 1999 by Roger Bowler, a ...
BNSF Railway ( reporting mark BNSF) is the largest freight railroad in the United States. One of six North American Class I railroads, BNSF has 36,000 employees, [1] 33,400 miles (53,800 km) of track in 28 states, and over 8,000 locomotives. [2] It has three transcontinental routes that provide rail connections between the western and eastern ...
Since the rise of the personal computer in the 1980s, IBM and other vendors have created PC-based IBM-compatible mainframes 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.

IBM 3270 Workstation Program with PC DOS 3.3. CPU. Intel 8088 @ 4.77 MHz. Memory. 256KB ~ 640KB. The IBM 3270 PC (IBM System Unit 5271), is a personal computer developed by IBM and released in October 1983. Although its hardware is mostly identical to the IBM PC XT, the 3270 contains additional components that, in combination with software, can ...
t. e. IBM mainframes are large computer systems produced by IBM since 1952. During the 1960s and 1970s, IBM dominated the computer market with the 7000 series and the later System/360, followed by the System/370. Current mainframe computers in IBM's line of business computers are developments of the basic design of the System/360.
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.
