Character generators were a clever way to save memory.

字符生成器是一种节省内存的巧妙方法。

This was called a character generator, and they were basically the first graphics cards.

这被称为字符生成器，​​它们基本上是第一款显卡。

To do this, the character generator had special access to a portion of a computer's memory reserved for graphics, a region called the screen buffer.

为此，字符生成器可以特殊访问计算机内存中为图形保留的部分，该区域称为屏幕缓冲区。

Just like how characters were stored in memory and turned into graphics by a character generator, these vector instructions were also stored in memory, and rendered to a screen using a vector graphics card.

就像字符存储在内存中并通过字符生成器变成图形一样，这些矢量指令也存储在内存中，并使用矢量图形卡渲染到屏幕上。
