VT 510/520 Video Display Terminal

The ADDS VT 510/520 Video Display Terminals, manufactured by Boundless Technologies, are high-reliability terminals originally designed by DEC. Boundless Technologies is a prominent player in the ANSI terminal market, offering these products with a 3-year warranty and a money-back guarantee. The company emphasizes its 30 years of experience in providing custom desktop solutions, making it a trusted choice for major server manufacturers.

The VT510 is presented as a cost-effective, single-session terminal ideal for open enterprise environments. Its features include downloadable micro-programs, status and indicator lines, off-screen memory, horizontal and vertical scrolling, local copy and paste, and built-in clock and calculator functions.

The VT520 offers advanced multi-session capabilities, effectively functioning as four terminals in one. It allows for creating four independent sessions over a single wire (with Digital's Session Support Utility) or through three physical connectors. Key multi-session features include split-screen viewing, session labeling, status indicators, and the ability to copy and paste between connected sessions.

Both terminals provide a broad range of terminal emulations, encompassing DEC VT100-420, various Wyse models (50 to 150), TeleVideo, and ADDS Viewpoint, making them suitable for replacing existing display terminals. They boast a 14-inch flat-face, high-resolution screen with reduced glare, a 72 Hz refresh rate for flicker-free viewing, and options for green, amber, or white phosphor. Communication options include multiple serial host ports (RS-232C and DEC RS-423), a parallel printer port, various flow control methods, and baud rates up to 115.2K. User-friendly features include integrated desktop accessories like a calculator, calendar, and clock, along with fully programmable keys. Boundless Technologies ensures rapid delivery from its Western NY manufacturing facility, offering customizable phosphor colors and keyboard options, and the products comply with numerous regulatory standards.
