Contents of the TARGET3.DOC file

Target3 provides an excellent EGA/VGA alignment tool.

... The outside rectangle reflects the maximum horizon-
tal and vertical parameters of the graphic display
(640x350 EGA, 640x480 VGA).

... The large circle provides a means of accurately ad-
justing horizontal and vertical size proportionately.

... The fine crosshatch may be used for adjustment of
'pincushion' and linearity.

... The corner spirals are a good target for focus and
color purity.

Examination of the Turbo Pascal .pas file will show that the
program forces VGA mode 2. To operate in EGA, remove that sub-
routine and recompile.

Note ... the Borland .BGI driver must be in the same direc-
tory as Target3.Exe to perform correctly.

Please feel free to modify ... any suggestions would be ap-
