Thou shalt have no other gods before the ANSI C standard 1492

OK. Here's a "is this true?" sort of history question.

I'd read somewhere that the use of CR followed by LF was because the early Teletypes (before the 33, but I buttume it did the same) could accept and process the LF while the CR was still in progress.

That is, after the carriage had started returning to the left, the circuits which processed characters where free and could process another character, but since you couldn't do anything that would move the carriage (space, or any printable characters) until the carriage hit the left side, what it could actually complete processing were basically limited to LF and BEL. Both because the hardware which rang the bell and moved the platen up a line were entirely independent from the platen movement mechanism. So, they put LF after CR to basically get the LF done while the carriage was still returning.

You could do it the other way, but there was little advantage to it, because the LF didn't take that long, mechanically, compared to CR,

Anyone who knows the old KSR or ASR's know enough about the circuits and mechanics to know if this is true or not? It sounded plausible, especially in the 75 and 110 BPS days, but it's also kind of got that "Urban Legend" feel to it.
