First off, thanks to Fotios for figuring out this mod in the first place! As I'm sure you've seen, a few colors are off.
Mainly:
Orange looks dark purple
Dark Grey looks light blue
Has anyone figured out how to fix this? Thanks in advance!
After some playing, I'm thinking of replacing the built in potentiometers. The ones that come on this board only go to 1K Ohm and after tinkering I think increasing resistance may bring colors in more.
Umm.. Maybe I took stupid pills this morning. I just hooked up my 1902 and the colors look like they are close to the same. I'm going to take a pic of the 1902 image and compare to the adapter output.

Ok here is the VGA output, after tinkering with the pots a bit.

Closer than I was thinking, mainly only color 11 is off. Quite doable as-is.

It's not a matter of fixing anything... The 16 colors in 80-column mode are different than the 16 colors in 40-column mode.
These are the most noticable differences:
40-column "purple" looks like "hot pink" in 80-columns.
40-column "orange" looks like "dark purple" in 80-columns.
40-column "brown" looks like "puke tan" in 80-columns.
40-column "pink" looks like "bright red" in 80-columns.
40-column "dark gray" looks like "dark cyan" in 80-columns.
40-column "medium gray" looks like "dark gray" in 80-columns.
These color names are, of course, my own opinion... I don't think you'll find a crayon that's labeled "puke tan". ;)
