The footage that exists of how the Commodore 64 was manufactured is low quality VHS. Retro Recipies has used software to enhance the video, providing higher quality.

You may have seen the original very low quality German VHS factory tour of MOS and Commodore that’s been around for years (https://youtu.be/xu8Fi0tC9IA). Sadly a higher quality version never showed up. I’ve been wanting to do this for a while but the technology only recently got to an acceptable level. It’s far from perfect, and the machine learning sharpening can look a little odd occasionally, but I hope you agree that it’s better and more palatable than the original, all just in time for the C64’s 40th anniversary. I plan future versions as the tech improves.

I used Topaz Labs machine learning video enhancer (https://www.topazlabs.com/video-enhan…) to create 5 versions of the footage. Some levels of restoration can make the people look cartoony, so by using different levels, I was able to cut each shot to its most natural look and ensure I felt it really was an improvement over the original. Occasionally I use the original shot with only upscaling to 4K. Some shots actually use different levels on different parts of the same frame using masks, so you might see sharp C64 motherboards, but the worker’s more natural less reworked face above them, all in one image.

You can see the results in the video above. Via 6502.org
