  1. thank you @tf_hh - this additional info is excellent. Gotta keep these Jr's alive and performing well.
  2. Finally got to ordering a Basic board..... shipping is killing me 😣
  3. ....CD4050 reinstalled, continuity from TIA checked - everything as expected, per your info @alex_79 (thank you again!). I've tried some removal of header / jumper pins from my existing UAV (Plug in) with no decent progress for the effort (i only have braid, i'm also concerned with the heat i'm pouring into a tiny board). I'm going to order a basic UAV and continue work with that i think.
  4. This is great information and very helpful - thank you @alex_79 . I'll definitely reinstall the CD4050 as @DrVenkman has recommended. My board is the plug in style, but i'll see what i can do to desolder the headers from it as there's no a lot of spare room in a Jr case. All going well it might be a v1 upgrade. Bare board(s) will be ordered on proving this successful, for swapping in (i have other Jr's that could use svideo). Hopefully i'll get a chance this weekend (early Friday morning here right now) - I'll post updates back when i do.
  5. I *might* have already kicked another project off, thinking the UAV was straightforward and was done....... I’ll try and do some tracing when I can get some time. See where that takes things.
  6. The CD4050 is removed. I’ll check the BnW output as soon as I can in the morning.
  7. I'll have to get a picture of the image on my display, but in Pitfall! - I only get one shade of green for both the treetops and the background (the background is a lighter green in all imagery I've seen, but not on my Jr with mod). The background and treetops are both the darker green used for the treetops, no separation. The brown tree trunks are as expected. As previously stated - the quality is excellent. I've adjusted the colour ('color' for you US folk) pot and there's is no position that corrects the tree colours either. I'm loading the PAL rom via a HC encore.
  8. @alex_79 instructions were followed as per the 2600 jr specific parts of the included UAV guide, but yes - there is nothing indicating variations in jumpers for 2600 models or for a PAL B jr. I don't have the expertise to know more than the guides for these sorts of products. I have a rudimentary understanding of electronics, and can solder, desolder, replace through-hole style components, perform basic testing etc, but I'm not sure where to start on tracing functions. I'll try reaching out to the The Brewing Academy for extra guidance also.
  9. @TheMontezuma Did this ever get a resolution? I’ve just finished fitting a rev d UAV + IAB into a PAL 2600 jr (well, I still have to work out top case refitting, but it’s useable) It is exhibiting the same colour issues.... while the picture is sharp, colour is pretty much on par with the screenshots in this thread. Colour pot adjustment has been performed. My UAV board isn’t getting hot or anything though. I’m using svideo output to a retrotink mini, connected to a Samsung Syncmaster LCD.
  10. As someone who's wondering how we keep these devices reliably running(C64 & kin included), this sounds very interesting.
  11. These are truly great work @Omegamatrix. Thank you for your efforts!
  12. Apparently THIS is where now
