VT520
The VT520 is an ANSI standard computer terminal introduced by Digital Equipment Corporation (DEC) in 1993 and 1994. The VT520 is a multi-session monochrome text-only terminal with a built-in 14" monitor. The VT510 was a single-session version, while the VT525 added color support and used a separate external monitor.

The VT500s replaced all existing models of DEC's VT line, which at that time consisted of just the VT420 text and VT340 graphics terminals. It was introduced in an era when the market was being flooded by low-cost IBM PC clones which could perform the same functions using a terminal emulator while also running other software. DEC introduced the VT500s only a short time before selling off their entire terminal division in August 1995. This brought the VT series to a close, after a total of about six million terminals had been sold.
The VT520 was available from Boundless Technologies until the company went defunct in 2003.
