About the S-VIDEO port.. I say "super video" many times in the video. This term is incorrect. I've since learned, it's "separate video". So.. I know it. ;-)
EDIT July 14th 2017:
There is now an improved version of this board, which is available as of august 2017: https://icomp.de/shop-icomp/en/produkt-details/product/c64-reloaded-mk2.html
An alternative to this motherboard, is this new project. An FPGA based solution: http://1541ultimate.net/content/index.php?option=com_content&view=article&id=74
Yes, it was a BAD idea to cut into the case, and I really regret it. I should have cut into the plug instead. Sad, but what's done is done. Moving on.
In this video, I unbox the C64 Reloaded board. I also set it up, test it and compare picture quality with a normal C64. This motherboard is conceived, produced and sold by Individual Computers (Jens Schönfeld). This is great hardware!
