The reason for this is that the carriage return is SLOW. But it can be overlapped with the paper feed.
Seems like I recall hearing an explanation like that.
From experience I know LF is 'fast'. Fast enough that one could make the paper basically shoot up like a fountain from the TTY33. Operators really loved it when the users discovered that and how to send messages to the operators.
You are going a bit too far back - typewrites done the LF/CR thing using human control (hand) so there were no input until the movement done.
But! with teleprinters (electronically controlled) the data flows in without interruption, but the mechanical movement of the printing head still there, so the only proper form is CR/LF... The reason is that the printing head need more time to travel back to the beginning of the page than the time it takes to print a letter. That time bought by the processing of LF...

While I learned how to type on a Selectric in high school, at home I was relegated to a portable mechanical typewriter which was early 60s vintage.
The mechanics of the carriage return would behave differently depending on both the location and force applied to the lever. If you were light of touch or applied the force towards the pivot point the CR would be first. If you were heavy handed towards the front end of the return lever the LF would have occurred first.
I suppose I could track down which of my older sisters still has this museum piece to do a follow up investigation...
Maybe CR becomes before LF due to the alphabetics of the code names?

One reason I could suggest is because the CR by itself is useful. If one wants to 'bold' something one does a CR and then spaces out to where the bold word should be, then types the bold word again (so on top of the existing one) and then one could either do another bold word (same process) or do an immediate CRLF.
Alternatively an LF by itself, arbitrarily in the middle of a line wasn't useful.
Especially because if an LF was done in the middle of a line and that was the last output in the block and another block, some where else in the app, needs to print then it doesn't know where to start printing. This lead to things like always putting a CRLF at the beginning just to be sure that one 'knew' that it was at the beginning of a line and on a fresh line.
So basically CR was more important than LF.
[UPDATE:] Still like my guess but after reading other responses and checking my fuzzy memory I agree it was probably speed of operation between the two.
I have purchased royalty-free songs for use in my stuff at:PremiumBeat.com[^]
There is tons of music there and you can get short to long tracks and loops and all kinds of great stuff for a one-time fee. Check it out.
Do you know of any like that one but completely free?
It's only $15. Why not just buy the license and save the time of finding something free? Besides, we gotta remember to keep the artists of the world creating with our support. They got bills too. And a life without music... sucks.
If you want to make money with bitcoin now, you're better of trading it. Although, I'd be watch the market like a hawk if so to ensure the rally isn't over with. Profit-wise you buy low and sell high, not buy high after the spikes.
I took a good look at mining; either bitcoin or etherium, litecoin, dash etc., etc. Given the cost of electric where I live (around 18c per KWh) and the cost of the kit to do the mining, it wasn't worth it at the scale I could afford to do it. One of the issues is that if you build your own rig, the cost of video cards has gone through the roof. If you buy kit, the noise and heat it produces means you would have to devote a room to it and ensure that it is properly vented. All costs money. Even running 24/7 I would not have made enough in a year to make it worth while and that doesn't take into account when the networks change the level of difficulty.

I am giving Ether mining a spin. Started like yesterday.
Everyone advises against CPU mining, but I see it as a learning experience, and fun. My 12 3.2GHz cores are hungry for food. On all fora ppl say that the Go implementation is a piece of Elephant. But on github there is zero activity on the C++ implementation and a lot on the Go one...
And if you have Ether mining experience I am happy to hear it.
