>glad to see that this topic is still alive I did the VGA Mod as explained by techknight and it worked very well with my 575 Board.
I thought this mod was for the original analog board that came with the color classic. Did you put a analog board from a 575 in your color classic?

>In understanding what is the error I think that it could be the VGA Mod. Could it bee that this "new" VGA Mod operates not with a Takky? Or anyone has a idea
>what the problem could be?!
Again, I thought this mod was for the original analog board that was stock on the color classic.
What am I missing? Did you do any mods to the 575 logic board that you are using? Or is it stock?
I haven't had time to get back to those monitors. The B+ has to be raised, but I think it can be done without trace cuts, just as this one has. Then the horizontal output safety capacitors need adjustment just like this one did to compensate for the higher frequencies, and the requirement for a slightly higher HV requirement, and then the adjustment in the Sync circuitry and it should be fine.Hey, tk. How is your application of the documentation on this hack going on your 12" RGB "640x480 conversion done right?"
Is that the original, "unauthorized" conversion done by the CC crowd back in the day?I've done the 60hz 640x480 mod to my CC Mystic. I get the option of 800x600 56Hz and it's pretty hard on the eyes. The 56Hz refresh isn't so bad since it's such a small monitor, but the UI text looks terrible as it's finer than the pixel pitch of the CRT.
