VT240

Last Updated: 02-May-2025

The VT240 is a graphics terminal made by DEC. It supports ReGIS vector graphics and emulates a Tektronix 4010/4014. My VT240 has a green phosphor monochrome monitor.

It seems that the case has been painted. The plastic underneath the paint is noticeably
yellowed. I'm not sure if it came from DEC this way or if someone painted it in the
past. I'm assuming it came from DEC like this, as I found it in a closet at work.

ReGIS Graphics

I wrote a python script to convert an svg file to ReGIS commands to demonstrate the graphics capabilities of the terminal.

Tektronix Emulation

This is an example of the tektronix 4010/4014 emulation. The text is unreadable and the graphics are not the correct aspect ratio. I'm not sure if there is a monitor available that would display the graphics correctly.
