The VT100 is the classic serial video terminal. It implemented a standard for escape codes to control the terminal, and VT100 emulation survives to this day. It was used to communicate with any machine that had a RS-232 serial interface, and was used extensively with the VAX line of computers.
It had an 80-character by 24 line display, but it could also do 132-character width, double-height, double-width etc. It had some basic box-drawing characters to allow some very basic graphics to be drawn. It was built around the Intel 8080 processor, which executes the firmware that implements the control of the terminal.
The VT102 is one of the cost-reduced variants of the VT100, it has no expandability, but it is a step up from the more basic VT101 because it has the Advanced Video Option (AVO).
