AN INCREMENTAL PLOTTER FOR THE PDP-12 COMPUTER



A NUMBER OF POWERFUL ANALYSIS AND REPORTING PROGRAMS AVAILABLE TO

US REQUIRE AN INCREMENTAL PLOTTER AS THE REPORTING DEVICE.

THEY USE ITS UNIQUE CAPABILITY TO DRAW A MIXTURE OF LEGENDS , SYMBOLS,

 AND DATA. THE PROGRAMS PROVIDE NEW CAPABILITES IN ANALYSIS AND 

INTERPRETATION OF EXPERIMENTAL DATA SUCH AS THE EEG,AS WELL AS FASCILITATING

PROCEDURES FOR REPORTING COMPLEX DATA IN GRAPHICAL FORM.



OUR COMPUTER HAS BEEN PREWIRED TO ACCEPT AN INCREMENTAL PLOTTER.

WE WILL SAVE 40 PERCENT OF THE USUAL PURCHASE PRICE BY ORDERING

THE PLOTTER AND CONTROL DIRECTLY FROM THE MANUFACTURERS AND 

INSTALLING THE COMPONENTS USING OUR OWN PEOPLE.       AN INCREMENTAL PLOTTER FOR THE PDP-12 COMPUTER

LOG THE ANALOG OUTPUTS OF A REPIRATORY FUNCTIONS COMPUTER
ON PUNCHED PAPER TAPE.

COMPUTER OUTPUT IS A PULSE OF DURATION ?? M.S. WITH AN AMPLITUDE
RPRESENTING THE COMPUTED VALUE. THIS AMPLITUDE IS TO BE 
DIGITIZED AND LOGGED. INITIALLY, THE RESISTANCE CHANNEL AND 
A CLOCK CHANNEL WILL BE THE THE ONLY AUTOMATIC INPUT. PROVISION 
WILL BE MADE FOR GENERATING BLANKS FROM A PANEL CONTROL; USEFUL  FOR 
VISUAL MARKING. THERE WILL BE AN OPERATOR OPTION TO DIGITIZE EVERY PULSE 
OR EVERY NTH PULSE. THE OPTION SELECTION WILL BE AUTOMATICALLY LOGGED.

DURING THE OCCURENCE OF A PULSE, IT WILL BE SCALED 
BY ANALOG AMPLIFER CIRCUITS AND PRESENTED TO AN ANALOG TO DIGITAL 
 CONVERTER. THE OUTPUT OF THE CONVERTER WILL BE 
IN ABSOLUTE UNITS BUT WITHOUT A DECIMAL POINT. THE THREE DECIMAL 
DIGIT OUPUT WILL BE PRESENTED TO A FORMAT AND DRIVE CONTROL WHICH WILL 
APPEND A TWO DIGIT IDENTIFICATION CODE AND LOG THE RESULT ON THE 
PAPER TAPE PUNCH A TIMER CHANNEL WILL BE LOGGED ATOMATICALLY IMMEDIATELY  
AFTER THE RESISTANCE CHANNEL.  

ANOTHER FRONT PANEL OPTION WILLBE A MEANS OF ENTERING CODED
STATEMENTS INTO THE PAPER TAPE LOG TO DOCUMENT AND LOCATE
SPECIAL FEATURES OF THE EXPERIMENT.

THE PAPER TAPE LOG CAN BE PRINTED ON ANY OF OUR TELETYPES,
AND IT CAN BE READ AND PROCESSED FURTHER ON ANY OF OUR COMPUTERS.
