I wonder how they did this. It seems like it would require some sort of hardware database.
Dialing Device Shows Stock Quotations on Indicator
SITTING in their offices business men may now learn at any time the status of any stock in which they are interested simply by dialing a number corresponding to the number of the stock listed on the New York Exchange.
Numbers showing the high and low of the stock and the figures at which it opened and closed are revealed on an indicator board as illustrated in the photo at the right.
The dial is similar to the dial used on telephones and rests in a convenient spot on the desk. The numbers are dialed much in the manner that phone numbers are called, so that the utmost convenience is afforded.
Each “teleregister,” as the device is called, is hooked up with the central exchange, so that the dealer has instantaneous connection with the stock market.
