I don't know as its that Jeremy, as much as its the Microsoft Windows Live
Mail 15.4.3538.513 you are using screwing things up by using M$ only fonts
the rest of the world, who pays attention to standards, doesn't fully
understand, so the meaning of your message becomes a bit obfuscated. See
for instance what I assume is supposed to be "I'm" in the echo above. That
is what I see scattered throughout your messages when a punctuation
character is meant, but which one?
As for your problem, I have never seen it, but since I am a CET, my best
guess would be a dried out capacitor in your coco's video circuitry,
causing the modulation to be much less than the 90% or so it was designed
for, which in turn gives a very low contrast, and likely hard to sync to,
image on a tv. That may not be it, but the track record of low capacity,
low voltage electrolytic capacitors commonly used in such places, its about
20 to 25 years overdue. That in itself says much good about the quality of
the parts used to build the early coco's all those years ago.
If you have an oscilloscope, looking at the signals on each end of those
capacitors, you should see an identical signal on both ends of the cap,
only with a small offset in the DC voltage that signal is sitting on.
