for various international uses and basic form graphics. The system shipped with five sets of 94 characters, as well as a single set with 96 graphics characters. The sets were ASCII, ISO Latin and three graphics character sets. Using sixels, any one of these sets could be replaced with user-generated

The screen itself was a 14-inch CRT mounted on a tilt and swivel stand. It offered a resolution of 800 by 500, and a number of different glyphs could be used to produce 25 lines of either 80 or 132 columns of text, the 25th line normally being used to display status codes, like caps lock, generated

The VT320 was introduced at $ 495, something of a surprise, forcing Wyse to lower their prices to $ 599.

available, the 300s added the ability to store several pages of data locally, as well as perform editing on that data entirely within the terminal. The user could scroll up and down among several pages, normally about three, perform edits, and then send all of the changes to the host in a single

that allowed single characters in a set to be swapped out to match the layout of a keyboard. For instance, in the UK the # symbol could be swapped out for the £, eliminating the need for custom versions of the terminal for each country. It supported the full range of

operation. This required compatible host-side software to work. That memory also meant all of the 300 series were able to store large numbers of sixel-based glyphs, allowing them to be used not only as a user-defined
