Also keep in mind that as the picture tube ages, the gamma relationship worsens; so what you see on these ancient monitors today is maybe not how they originally looked.Great Hierophant wrote:But what about the grays? I hear that on some digital monitors the difference between black and dark gray or dark gray and light gray are nigh indistinguishable.

The DAC part, not the synthesis part. The music will of course sound like a regular Tandy. D'OH!SirGraham wrote: I don't know how it's supposed to sound, but I was told that the Tandy DAC should sound like SB.
Original IBM PC motherboards (8088 processors) had a small trimmer capacitor on the 14.318318 quartz oscillator labelled "Color Adjust" - since the IBM CGA card derived its 3.58 MHZ NTSC color subcarrier frequency from the motherboard clock, which was distributed on the original XT expansion bus. All that to save a 39 cent crystal on the CGA card!

I think wd is to "blame" for the broken text issues.
I'm sure they will be fixed.

Changed from what
Great Hierophant wrote:Also, I believe I have finally found an answer to the question of which color does the IBM 5153 Monitor show for color 6. My source finally came through with captures of the 5153 with a digital camera, and here is what he shot:
This is the same screenshot modified to boot the green value from 84 to 168. As you can see, this gives a dark yellow color that is far closer to the capture than the previous screenshot.
