Olivetti ETV series typewriter

Here some documents about the typewriters Olivetti series ETV, from around 1985 on.

It's not very clear what does it means ETV. Most probably it means Electronic Typewriter Video.

These typewriters were word processing system, with a memory to register what you wrote, and a video to see it. It could include also a floppy disk, that could memorize 320000 characters (160 pages).
Basically it was similar to the ET typewriters, but with many additional functions.

It was a revolution: You could see what you wrote before printing, there was no need to delete incorrect words, no layout errors, the possibility of storing a text for later use by modifying only the necessary parts.

To print it used the daisy wheel, ensuring silence, and ease of changing character according to needs.

Software features are similar to the Windows Word we are using now:
- Automatic return to the next line when the missing word cannot be contained completely in the line being typed.
- Key search
- Automatic and manual substitution
- Deleting, moving, and storing parts of a text
- Composing and assembling paragraphs
