Fax machines are 19th century technology?
Yes. I think fax machines came right after telegraphs. They used pendulums connected to telegraphs I think. Look it up.
I read that years ago. Found this on the interwebs:
1843
“The first recognizable version of what we consider the telephone fax was invented in 1964 by the Xerox company, but the technology that led to that advancement was created much earlier. In fact, it was Alexander Baine in 1843 who invented the electric printing telegraph.”
