Hi,

Thanks, the gif looks like what I wish my digital camera could capture off
the TV screen.

Please describe the exact steps that you used to do the capture and the
color resolution at each step.

Somehow we lost some colors as Paint Shop Pro 8 says there are only 59
unique colors in the gif. Should be at least 64.

Also why are there dots on number 3?

I was planning to do what I think you did, but are we not just reading out
the color values that (Jeff and / or John Collier) or the MESS authors coded
into their programs?

If you redo the capture and discover where the missing colors were lost,
just tell me what you did, don't send another image unless I say OK.

I really do think that we are just recovering the coded values in the
program and will find out that the 24 bit color numbers match those in the
emulator listings.

If a digital camera could do a better job, much better than what I made
available, then that would be very useful. TV rasters are very bad and 
cannot be improved as the CoCo 3 is only generating one field. Frame?

But I keep coming back to, is there not a standard way to map a two bit A/D
into a 8 bit A/D?

Your gif is so good that I will be printing it along with my Digital Camera
image and comparing it to my RCA TV S-Video display and my Sony KV-1311CR TV
with RGB display.

It will be my temporary replacement for page 295.

NOTE!!!!!! I will be changing the background to white and the text to black.

I also will be using filters in PSP 8 to try and remove the raster lines in
the digital picture and come up with a single 24 bit value for each Swatch.

When I get the chart  ready for printing then some CoCoers can compare the
results and report.

Thanks to all that have helped. As soon as I can find out why Paradox will
not run for my normal user but will for ADMINISTRATOR I should be able to
build the chart very quickly. I want to use Paradox as with just a few lines
of code I can change the RGB color values and have the Swatch color change
immediately. That system has a CRT monitor, I think that comparing on a LED
display may be useless.
