The computer-terminal dynamically-redefined-character-set (DRCS) technology could be used to create sprites.

I.e. the spites would be part of the soft-character-set.

And it could be extended to support other file data formats besides just sixels.

(The computer-terminal dynamically‐redefined‐character‐set (DRCS) technology is similar in idea of a unicode private‐use‐area.)

An important thing about many #ComputerTerminal is that — a lot of them (probably most) could only display text!, and only in a single color!

(Although I suppose it is 2 colors, if you also count the dark color of the screen.)

(And also, the 1 color of different Computer Terminals could be a different color from each other.)

So the Computer Terminal world was very monochromatic & text oriented!

Back in the 1990s it was not uncommon to still see Computer Terminals in use.

A #ComputerTerminal kind of looks like a computer; but they aren't computers.

You can kind of think of them as a combined monitor & keyboard.

They connected to a computer located somewhere else.

Sometimes many Computer Terminals connected to the same computer.

For a long time, the de facto ‘text’ data format included the Select Graphic Rendition (SGR) control sequences.

In practice, SGR control sequences were as much ‘text’ as the carriage-return, form-feed, horizontal-tab, line-feed, vertical-tab control codes are ‘text’.

SGR control sequences gave us things such as — bold, color, italics, overlining, underlining, etc.
