I have an original Taito Bubble Bobble boardset wired up to my test rig and while it works okay the color gradations don't appear to be all there - all sprite colors appear to be 'washed out' (blue especially) and if I go into test mode and look at the test color pattern there is only one color gradation on the far right side, when there should be four color gradations in total.
So, top to bottom it's:
Red
Green
Blue
White
Then from left to right on each color it should get darker in three more steps for each colour (with white turning a darker shade of grey).
Is this likely to be a problem with my monitor (which works just fine on all of my other assorted boards)?
The color resistors on the board are rated at 75 ohms as they should be.
Or should I be looking for a logic problem on the video board?
Thanks
