The Digital Equipment Corporation VT420 terminal was released in 1990 and probably discontinued around 1993 or 1994. It was a Text and ANSI graphics only terminal like the VT320 and VT220 before it. It added a 50 line display capability and the ability to have two sessions on the screen, one for each serial port. This sample was produced in Taiwan. It used the two MMJ connectors for its serial ports but an option added a DB25 port for the first serial port. Mine is MMJ only. There was no graphics version. DEC kept the VT340 in production along with the VT420. This sample was produced in Taiwan. I think DEC may have moved production from China to Taiwan for all of their terminals.
Notice now that the logo is printed instead of emblossed like the previous terminals. The Digital logo is still embossed though.
