Description
CRT Horizontal Sync (polarity is programmable)
or "Composite Sync" for support of various
external NTSC/PAL encoder chips.
CRT Vertical Sync (polarity is programmable).
CRT analog video outputs from the internal color
palette DAC.
The DAC is designed for a 37.5 equivalent load
on each pin (e.g. 75
parallel with the 75 CRT load)
Set point resistor for the internal color palette
DAC. A 528
RSET and DACGND.
General purpose I/O, suitable for use as DDC
Data.
General purpose I/O, suitable for use as DDC
Clock.
These two pins are functionally suitable for a DDC
interface between the graphics controller chip and
a CRT monitor.
1% resistor is required between
resistor on the board, in
