towmater Posted March 13, 2017 Share Posted March 13, 2017 I'm doing a composite-out mod, which seemed easy enough as the instructions commonly describe attaching to the leg of C45 and C44. Only on my board these are resistors, even though they still have silkscreening indicating capacitors. It could go either way, it might have been found to create a better signal with resistors, or the manufacturer found they could save x pesos by changing the parts at the sacrifice of video quality.

metarog Posted March 13, 2017 Share Posted March 13, 2017 Wow, I've never had a 703965-5 board revision before out of the dozen or so O2s I've composite modded. Let us know how the mod went. Quote Link to comment Share on other sites More sharing options...
towmater Posted March 14, 2017 Author Share Posted March 14, 2017 Seems to work fine, the composite is certainly better than the RF, not sure if it would be better with the caps, if you know the specs of those two caps please let me know and I'll do an A-B comparison.

Keatah Posted March 14, 2017 Share Posted March 14, 2017 (edited) I'm doing a composite-out mod, which seemed easy enough as the instructions commonly describe attaching to the leg of C45 and C44. Only on my board these are resistors, even though they still have silkscreening indicating capacitors. Those are axial capacitors with color-code bands. https://en.wikipedia.org/wiki/Electronic_color_code Heh.. Once I looked at an Apple //e motherboard and saw what I thought were bypass filter diodes across each IC. Upon close inspection I found a surface-mount cap in glass envelope, sized like a diode, looking like a diode!

metarog Posted March 14, 2017 Share Posted March 14, 2017 you using the free composite mod I posted? No, just the basic mod with no additional components... the colors are a little dim but otherwise it looks nice enough. Quote Link to comment Share on other sites More sharing options...

Ah, ok If you ever get tired of a little dim, check out: https://www.oshpark.com/shared_projects/d64FOCcN If you just want to wire audio direct, this one is composite video only: https://www.oshpark.com/shared_projects/7kDLANgI Quote Link to comment Share on other sites More sharing options...
