Is this to speed the carry ripple? Have you a name for this technique so I can Google, or a reference?

I couldn't find anything that mentions counters in particular, but it's described for adders in general e.g. here, slides 10-11: http://www.cs.tufts.edu/comp/103/notes/Lecture13(Adders).pdf

Very interesting explanation of a very clever technique. The demo itself is also a gem!

To your surprise? Oh, please... Hands down, your demo was the absolute winner.

A case against syntax highlighting

This argument is specious and it is absurd beyond all reckoning. Coloring every word of a paragraph in natural language is in no way similar to syntax coloring in a programming language.

I just cannot believe that anyone could take this argument seriously.

exactly. what a joke.

i couldn't finish the rest of the article after reading that sidebar.

Well said, my friend.

When I started programming, color highlighting would have been impossible because all monitors were either white, green, or amber.

But even with modern IDE's, I find coloring to be distracting.

Now, there are SO MANY code variations, that assigning any meaning to them is rather meaningless. They are lost amid a WASH of colors.

To add to your "exceptions", here are the only other areas that I find color highlighting helpful. It is helpful not in reading code that is actually there, but helpful in finding code that is MISSING.

Unterminated strings. Missing closing tags/statements. That sort of thing.

About the only time that color coding helps me is when I see a long block of code that is obviously the *wrong* color. Pretty much the same observation you made about landing in a patch of commented out code.

And, hello from Tulsa, Oklahoma, USA.

As this topic still seems pretty active, maybe I can assist future posters.
Maybe replacing the broken Potentiometer with this one:

RV12 10K 103 B103 Switch Rotary Radio Potentiometer

Hope this helps.

Can any byte in ram matching the $0007 pattern be changed?
I guess what is banked out would not suffer?

One of my favorite old chiptunes and IMO this was amazing! Sure it gets a little loose in spots, and the recording quality isn't the best. But, I think the way you managed to emulate aspects of the original's sound with the piano is fantastic, and to perform it all so well in one go is impressive!
I'd love to see a video recorded version :)

Frankly, that's EXACTLY what all syntax-coloured code looks like to me.

It colours according to distinctions I make effortlessly anyway,
and reduces contrast to the point where i have a hard time reading
ANYTHING.

Before syntax *colouring* we had syntax *styling*, which provided
all the help that colouring is alleged to provide without being
anywhere near as visually distracting. One extremely useful
thing -- in a language with seriously messed up syntax like the
C family -- was displaying the definitions of identifiers a point size
or two larger than their uses. I found that extremely helpful but have
yet to find a syntax colouring tool that does the same.
