[GreenKeys] Carriage return questions

[Mike Dodd]

Can someone refresh my memory about how the carriage in older TTYs and 
the type box in newer machines was moved to the start of a new line upon 
receipt of a CR character?

Was it a powered movement, or did a spring haul it back? Seems like it 
would have to be pretty quick -- perhaps only 0.28 seconds -- to get it 
moved before the next character after the CR LF sequence.

Just curious; it's been a long time since I saw one in action.

Thanks.
