[GreenKeys] Lamp bulb in M15 table...

[Jack]

It is definitely running faster than real life…

 

I’ve never seen the “traffic lamp” feature on a Model 15, but it was

an option on Model 28’s. It used the top red “lense” on a 28RO/KSR with a 115VAC

lamp and resistor. It was controlled by a normally-closed stuntbox contact. The ones

I observed would flash the lamp whenever a SPACE character

was received.  I only saw this feature in a facility where there were at

least a dozen 28’s pecking away. I think it gave the attendant an

indication that all circuits were active. Another application was

to use that lamp/lens for a paper-out indicator. Or, it could be used

with a stuntbox that was coded for multiple BLANK characters,

which would indicate a line might be open.

Also, I'm betting that that was faster than 60 WPM,  AND. the type was much larger  AND/OR the paper was much

narrower than one would see in a Model 15.  Something special for the FBI?

     I just stumbled on something. In the opening of a movie called "The 
House With No Name", just past the opening titles, there is a shot of a 
Teletype working. Just to its left is a light bulb flashing in time with 
the printing. What is this?
