  1. Bob1200XL provided a further update on this to me yesterday. It is even easier than before.

     

    *Ignore* the previous references to CR20, C115, and U27. (So that answers your specific question.)

     

    I did the following and it turned out great on my 1200XL:

     

    Remove L15 and replace with a wire.

    Remove C60 and replace with *nothing*.

     

    I also connected the missing chroma line at R45.

     

    This mod gave me excellent Chroma/Luma; and pretty good composite. I would say that this mod produces video that is at least as good as a stock XE -- maybe a little better. (IMO) It is not quite as good to my eye as Clearpic 2002, but close, and at least by comparison to other video mods, is very easy.

     

    We need a name to differentiate this -- what should we call it (anyone)?

    Larry: Thanks for the update.

     

    Edit: Just did the mod. Using composite, it is almost as good as my SV 130XE. The 1200XL is brighter and vivid in comparison. The major difference I can tell is that the white characters on the modded 1200XL have some color bleed.

  2. and add a 1K resistor from pin 11 of the 4050 (U27) to +5v (wired on the bottom of the board).

     

     

    Please help me with this step. I am not sure what you are referring to. With the chip oriented right-side up and the notch on top of the 4050 (at U27), which side will pin 11 be on and which one is it if I count from top down. Also, where is the +5v? Sorry if this is too newbie of a question. I need a visual aid. I have completed the 800XL and 130XE SV mods using pics. :cool:

     

    Thanks.

  4. What will become of all of your stuff? I would like to keep it for as long as I am still coherent. But for those that do not have children, should we donate it to some historical society? Give it away? Ebay it before we pass away? I remember when I was a kid, there was this old man that had a very valuable HO train collection. As far as I know, he did not have children because he was always misreable and alone. He was just some old man that lived alone with his dogs. I was the only kid that would talk to him and the other kids were afraid of him. One day, he passed away all alone in his house and I guess the stuff just went to the state that probably sold it at an estate auction. I know if I pass before my wife, she will just throw it out. Since you guys are probably in your 40s like me, do ever give this any thought?
