A DEC VT100 with the VT-640 Retro-Graphics board installed. The VT640 Retro-Graphics, originally known as the VT100 Retro-Graphics, is an expansion board that was developed by Digital Engineering, Inc., for Digital Equipment Corporation's popular VT100 terminal, allowing it to be used as a graphics terminal capable of a resolution of 640 by 480 pixels.
VT52 codes remained proprietary to DEC, although a number of other companies provided emulations in their terminals. Later VT series terminals supported a subset of these commands. One interesting case is the GEMDOS system and its offshoot, the TOS operating system of the Atari ST.
The VT200s were the last DEC terminals to provide a 20mA current loop serial interface (using a 8-pin Molex-style connector), an older standard originally developed for the telegraph system but became popular on computers due to the early use of Teletype Model 33's as ad hoc terminals. A standard 25-pin D-connector was also provided for RS-232.

IBM 5251, connected to an AS/400 system. IBM 5250 is a family of block-oriented terminals originally introduced with the IBM System/34 midrange computer systems in 1977. [1] It also connects to the later System/36, System/38, and IBM AS/400 systems, and to IBM Power Systems systems running IBM i, as well as the Series/1 minicomputer.
The System Three was designed for multiuser professional use and included an optional hard disk, CRT terminal, printer and the main computer unit. [ 22 ] Cromemco software includes CDOS, which was very much like CP/M, and CROMIX, Cromemco's own multi-user Unix-like OS.
Following its introduction the 3270 and compatibles were by far the most commonly used terminals on IBM System/370 and successor systems. [15] IBM and third-party software that included an interactive component took for granted the presence of 3270 terminals and provided a set of ISPF panels and supporting programs.
Uniscope was a class of computer terminals made by Sperry Rand Corporation, Univac Division, and successors since 1964 that were normally used to communicate with Univac mainframes. As such, it was the successor to various models of Teletype. Due to the text color on the original models, these terminals are informally known as green screen ...
