I use Cadet modules for I/O on my system and recently added S-Video output to my Cadet II in place of the PAL/NTSC switch which has worked well.
I’d like to move on up to component output and after researching a bit, I think I’ve found a schematic I could reasonably adapt to add component to Cadet II. I know just enough about electronics to get into trouble so I wanted to ask if anyone had some pointers before I whip up a protoboard.
Would I be able to simply tap the Cadet II’s RGB lines that go into pins 6-8 on the AD724 before C12, C13 & C14 and put them into the RGB to YPbPr schematic below starting at the non-inverting input pins of the 3 LM6172s (skipping the input 75 ohm resistors and CD4053 stage)?
For sync insertion onto the Y channel thru Q4, could I tap the CSync pin from the Cadet II’s sync header instead of having the LM1881 in there?
