3270 Emulator
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) using coaxial cable, emulators originally required channel (rare), coax or synchronous communication adapter cards to be installed in the PC. Today, many emulators communicate with the mainframe computer through a TN3270 server using the TN3270 () variant of the Telnet ()protocol common on TCP/IP networks including the Internet, so special hardware is no longer required on machines with Internet access. Several vendors offered both coax and communications attached 3270 emulators and TN3270 clients as part of the same product. Connectivity One way of categorizing a 3270 simulator is by how it connects to the host. Some 3270 simulators use a channel adapter to connect directly to the host. ...

3R Computers
3R Computers, Inc., or RRR Computers, Inc., later Avatar Technologies, was an American computer company based in Westborough, Massachusetts, known for their Avatar series of dumb terminal-to-workstation devices. History As 3R Computers (1981–1983) 3R Computers was founded in Westborough, Massachusetts, in December 1981 by Edward G. Grace, Brad Hebert (born 1944), and Fred Schlaffer. All three had previously worked for the Data General Corporation, a large minicomputer manufacturer whose headquarters were in the same city. Grace was named chief executive officer and president, while Hebert and Schlaffer both shared vice president status. The company spent a year in research and development before releasing the company's first product, the Avatar Terminal Converter (TC1), in late 1982. Grace cited dissatisfaction with Data General's reduction in complex projects amid the recession of the early 1980s as his reason for quitting: "Some companies are cutting back on esearch and deve ...

Terminal Emulation
A terminal emulator, or terminal application, is a computer program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term ''terminal'' covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window. A terminal window allows the user access to a text terminal and all its applications such as command-line interfaces (CLI) and text user interface (TUI) applications. These may be running either on the same machine or on a different one via telnet, ssh, dial-up, or over a direct serial connection. On Unix-like operating systems, it is common to have one or more terminal windows connected to the local machine. Terminals usually support a set of escape sequences for controlling color, cursor position, etc. Examples include the family of terminal control sequence standards known as ECMA-48, ANSI X3.64 or ISO/IEC 642 ...

Mainframe Computer
A mainframe computer, informally called a mainframe or big iron, 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. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainframe design is characterized less b ...

Alpharetta, Georgia
Alpharetta is a city in northern Fulton County, Georgia, United States, and is a part of the Atlanta metropolitan area. As of the 2020 US Census, Alpharetta's population was 65,818 The population in 2010 was 57,551. History In the 1830s, the Cherokee people in Georgia and elsewhere in the South were forcibly relocated to the Indian Territory (present-day Oklahoma) under the Indian Removal Act. Pioneers and farmers later settled on the newly vacated land, situated along a former Cherokee trail stretching from the North Georgia mountains to the Chattahoochee River. One of the area's first permanent landmarks was the New Prospect Camp Ground (also known as the Methodist Camp Ground), beside a natural spring near what is now downtown Alpharetta. It later served as a trading post for the exchanging of goods among settlers. Known as the town of Milton through July 1858, the city of Alpharetta was chartered on December 11, 1858, with boundaries extending in a radius from the city ...

IBM 3270
The IBM 3270 is a family of block oriented display and printer computer terminals introduced by IBM in 1971 and normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. Due to the text color on the original models, these terminals are informally known as '' green screen'' terminals. Unlike a character-oriented terminal, the 3270 minimizes the number of I/O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable. IBM no longer manufactures 3270 terminals, but the IBM 3270 protocol is still commonly used via TN3270 clients, 3270 terminal emulation or web interfaces to access mainframe-based applications, which are sometimes referred to as ''green screen applications''. Principles The 3270 series was designed to connect with mainframe computers, often at a remote location, using the technology then available in the ea ...
