	The VT100 was so popular it became THE standard for terminals, and [[terminal emulator]]s.		The VT100 was so popular it became THE standard for terminals, and [[terminal emulator]]s.

	The VT100 used an [[Intel 8080]] processor, the later VT102 used an [[i8085\|8085]]. VT100 clones (and there were many) would use a number of different processors, not necessarily sticking to the original.		The VT100 used an [[Intel 8080]] processor, the later almost identical '''VT102''' used an [[i8085\|8085]]. VT100 clones (and there were many) would use a number of different processors, not necessarily sticking to the original.

	Surprisingly the VT100 could not actually handle 9600 [[baud]] full throttle. The serial hardware could, but the screen could not be updated at 960 characters per second. Thus [[flow control]] was essential unless working with a slow system (e.g. an old [[minicomputer]]..). Xon/Xoff was the most common method for flow control on DEC/VT100 systems. To handle the speed problem some people would put the VT100 into [[VT52]] mode (one of the VT series' features) because VT52 processing had less overhead.[1]		Surprisingly the VT100 could not actually handle 9600 [[baud]] full throttle.
