In the introduction we say:

But in between,
from the 1950s to the 1980s,
most people used line printers.
These devices only allowed input and output of the letters, numbers, and punctuation found on a standard keyboard,
so programming languages and interfaces had to be designed around that constraint.

Would it be useful to add a photo, so people can understand better what line printers were? For example: https://upload.wikimedia.org/wikipedia/commons/d/df/ASR-33_at_CHM.agr.jpg

That is a beautiful picture of a Model 33 Teletype. But a line printer looked like this

Nice! Should we add it then?

I really enjoyed seeing a line printer but I think this does not add to the lesson by itself mainly because I do not how they work!

You can't use this image in a core SWC lesson, because it's CC BY-SA
3.0 Unported 1, and SWC lesson content cannot have the SA (Share
Alike) restriction 2.

@wking Good point! How about this one. Its CC BY 2.0 - we can add the attribution in the caption.

@Mahdisadjadi I have never used one, but I imagine it's like telnet, but instead of screen you have a typewriter ;). We can also add a link to wikipedia article in the caption.

+1 for adding the link to Wikipedia!

That sounds better. I'm not sure about mixing CC BY versions (2.0
vs. 4.0). The GPL suggests explit “or later” language for that sort
of thing, but the closest I can find in CC-land is BY-SA's §1.c (which
lists compatible licenses [1,2]). The CC FAQ has 3, and I expect we
could include the image with a caveat in LICENSE.md about the image
being CC BY 2.0, but I'm doubtful that we can unilaterally promote the
license to version 4.0.

Alternatively, we can try to contact the author and ask him to re-license with CC BY 4.0

If you're that motivated, that would be great. I'd make sure the
maintainers are interested in including the picture before going
through that much work though ;).

Thanks. I already sent a message to the author.

I'd love to hear from the maintainers what they think. Personally, I like using such a photo at a workshop to explain the history of command line. I find it very illustrative.
