About 20 years ago dear friend Gyro saw me buy a 14.31818MHz crystal at Addison Electronics and asked me why I was doing that.
I noticed long ago the color encoding on the C64 was generated by the same clock source as the dot clock and this has a detrimental impact on the image quality.
When I bought a C64DTV in 2005, I noticed it had a great quality TV signal even if it only had a composite output. I noticed then the color encoding was asynchronous relative to the dot clock. The old idea resurfaced...
Now, discussing with a friend about the 8701 clock generator, it occurred to me I could make one that uses two independent oscillators to ensure async color encoding and so I did. I love the result!
The funny thing is I now know what to do to encode the colors for PAL compatibility on an NTSC system and inversely.

I didn't know you had become the supreme tyrannical leader of a kingdom disguised as a communist country. which happens to have recently tested nuclear bombs and long range missiles...
You might ask that I call you Glorious Friend but is it more than likely a few prefer to call you iGnOminiOus Fiend ? (note intentional improper use of capitals as a form of disrespect...)

That's the cover story. The truth is:

Haa! Recover the lost proteins for the good hard working people - brilliant idea!
The guy with the blue-grey beret looks absolutely thrilled!

That's not the only execution method.

How exactly did this thread turn from color encoding on the C64 to methods for killing corrupt military officers ?merman wrote:That's not the only execution method.

Anyways... one can always say it's about hardware...
If I may say so... Gyro's method recovers part of what's lost, merman's method is grossly wasteful.
