Abstract: This package contains the following five programs:
 
TABTST		It tests Digital Equipment Corporation's
	  	DIGIT01-Tablet in Remote-Mode.
DIGIT1		It can digitize x/t-records of e.g. measured data.
DIAPL1 		It plots the data produced by DIGIT1 on a
	  	HPGL-Plotter.
DIGIT3 		It can digitize structural pictures like flowcharts.
DIAPL3 		It plots the data produced by DIGIT3 on a
	  	HPGL.Plotter.
 
Digital Equipment Corporation's tablet DIGIT01 (Bit-Pad-One
type) can easily be used to make X/T-Recorder measuring-data
on paper available for computing.  Furthermore, e.g.
flowcharts outlined by hand can be digitized and so be
prepared for use in papers.  All digitized data can be
plotted in a selectable form using a HPGL-Plotter
(HP7475A,LVP16...).
 
Two subroutines are used to service the tablet.  TABGET is
used to read the tablet's datastream.  DIGITZ converts the
digitized positional data to centimeter-pairs relative to
the origin in the lower left corner.
 
The tablet can be connected to the Professional's Printer or
Communication Port.
 
The digitized data is saved in disk-files.  To distinguish
the data produced by the tasks DIGITx, different
data-structures (file-types) are used for saving.
 
The two plot-programs included enable the user to select
freely, picture size and origin of the pictures.  The plotter
used to test the programs was the HP7475A.
