Schematic and component location drawings are pro-
vided
in
this section. The source location of waveforms
referenced
in
the text are shown on both schematic
and
component location drawings.
A Z-150
PC
computer was used to supply the RGB
signals for generating the waveforms.
NOTE: Some input and output waveforms for some
boards are taken from the adjacent boards because
test paints having the same signal are more accessible
there.
