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.
