+grips03 Posted December 14, 2016 Share Posted December 14, 2016 New to O2. Still waiting for console to arrive. I seen some post about adding composite video using wires only, no video amp. Does that work? I've also seen some posts about adding RGB components to the system board, in order to allow the console to provide RGB video out. Does that work?

forrestsmith Posted December 14, 2016 Share Posted December 14, 2016 Grips I did the one below and I thought it looked good / great on my CRT Television, not sure how it would look on a modern TV. If using a CRT I really don't think anything would be gained by doing something more complicated.

Everett1954 Posted December 14, 2016 Share Posted December 14, 2016 Yes, I did this to mine and it works great on my LCD. http://arcarc.xmission.com/Web%20Archives/Deathskull%20(May-2006)/games/tech/o2av.html 1 Quote Link to comment Share on other sites More sharing options...
+grips03 Posted December 17, 2016 Author Share Posted December 17, 2016 I want to add RCA jacks to console, but don't want to interfere with voice module. Does the voice module hit anything in the bottom back of console? Quote Link to comment Share on other sites More sharing options...
metarog Posted December 17, 2016 Share Posted December 17, 2016 The Voice goes draped over those vents in the back. Anywhere lower than that slope will be fine. There is plenty of empty space on the back left for ports. Quote Link to comment Share on other sites More sharing options...

There is plenty of empty space on the back left for ports. Back left might have to be the spot. Recessed area in back might hit system board. Still thinking about it. 1 Quote Link to comment Share on other sites More sharing options...
+grips03 Posted December 27, 2016 Author Share Posted December 27, 2016 I used the Deathskull laboratory mod, i.e. just connect the wires and the video was too dim. I then added the Intvwiki composite video mod and it works better, however its a bit on the bright side now. 1 Quote Link to comment Share on other sites More sharing options...
+grips03 Posted January 21, 2017 Author Share Posted January 21, 2017 Drew up O2 composite mod today. 2 Quote Link to comment Share on other sites More sharing options...
Ikrananka Posted October 19, 2018 Share Posted October 19, 2018 Drew up O2 composite mod today. Hey grips03, what circuit is this mod based on? Quote Link to comment Share on other sites More sharing options...
+grips03 Posted October 20, 2018 Author Share Posted October 20, 2018 Hey grips03, what circuit is this mod based on? I can't remember. I can say it works good and one can print for themselves on oshpark.com, so should be pretty cheap. Quote Link to comment Share on other sites More sharing options...
Ikrananka Posted October 20, 2018 Share Posted October 20, 2018 I can't remember. I can say it works good and one can print for themselves on oshpark.com, so should be pretty cheap. I may well just do that and am hoping that it looks as good on an LCD screen as it does on a CRT My curiosity was piqued when I realised that your circuit looks to be the same as that used by Retrofixes which is markedly different to that used by coolretroprojects - the latter being based on this one from SolarFox. But, with a little more searching I managed to find the source of the circuit used on your board which is from Wery who is a member of the assemblergames.com forums.

Ikrananka Posted October 20, 2018 Share Posted October 20, 2018 Hey grips03, so I'm putting my digikey order together but noticed that you seem to have changed the BC548 transistor from Wery's original BC548B to a BC548C. I believe the latter has greater amplification. Do you recall why you made that change? Quote Link to comment Share on other sites More sharing options...
+grips03 Posted October 23, 2018 Author Share Posted October 23, 2018 Yeah, no idea. I thought I might have got mod from videopac.nl, but can't remember. Getting too old. Quote Link to comment Share on other sites More sharing options...
