I cannot visually trace the side of R80 which leads to a tiny round thru-hole, but I can visually trace the other side of R80 which leads to this large round pad with solder on it... The same pad on the flipside of my LC520 motherboard... I re-checked visually 3 times and found it leads to...

Yes, I actually did forget about that your excellent post. And that is due to me being very forgetful about pretty much everything. Sorry. It’s that bad memory that led me to get into YouTube in the first place because I originally made the videos for myself so I could remember what I’ve done in...

As shown in my VGA mod conversion video, while the stock CC board does work with the 67Hz 84V 640x480 mod, the black borders at left and right of the CRT display area are thicker than when using an LC 575 or LC 520 board. And while it’s not technically a massive difference, it is noticeable...

I did indeed test my LC520 motherboard in my Color Classic with the standard 60Hz 68.4V "VGA mod" (640x480 resolution) installed. But as you may know, the 520 and 550 and stock CC boards are NOT compatible with the standard VGA mod, and that's why I more recently released a video about my...

@Fizzbinn you’re amazing! And @kefkafloyd , thank you too! I just posted the question about the 550 Rev. B board on FaceBook, so let’s see if that brings forth the final answer more quickly…

I just learned something new. Even though @Drake and Uniserver both mention the need to remove the 3 resistors R67/75/79, the Japanese book Doping Mac (published in Japan in 1997) says that in addition to those 3 resistors, R80 also needs to be removed... I only have an LC520 motherboard...

I’m afraid I’m now back to being confused. I think you’re saying I’m incorrect about the need for choosing one of two analog board types which drive your LCD? So… There’s in fact only one analog board type that you have made and sell? Saying it another way, how does someone place an order...

This is why I don’t get it… We all don’t think exactly alike. :-)

I still don't get it, but I am now strangely compelled to watch I Love Lucy episodes on YouTube.

I must say, that's impressive work!

@Mac84 , you're a star! 🌟 Many years ago, one of my SE/30 boards showed the exact pattern shown below, and at the time I posted in another forum to ask if anyone had seen that instead of the regular horizontal stripes, but no one replied back to say they did. Thanks to your Repair Guide, I see...

I was born in 1971 but never grew up with Commodore. Still, I've always been rather enamored by them. Many school friends I had back in the early 80's had them. And while my first home computer was the 128K in 1984, I still was extremely excited to see the factory tour video below I...

@frontein1 Your work is so incredibly awesome! 👏

Great ot hear! So I guess it is then a decision that boils down to this: Do you want more volume, or do you want stereo? Because it's unlikely someone would hack their plastic case to fit two of those LC575 speakers into the front/bottom area. And if you therefore want stereo, you'd need to...

If the rod is truly used ONLY for structural support reasons, then it shouldn't affect anything electrically if left broken, I wouldn't think. The flyback I had with a broken rod was mounted to the board very solidly prior to my removal of it. Meaning, people with broken flyback rods shouldn't...

So that's the gotcha. You must choose one of two Analog Board types for the LCD kit. I recently converted my 68.4V standard VGA mod to the 84V 13" Hi-rez Mod. The 68.4V Mod was great for 640x480 at 32,768 colors, but only with my LC575 Mystic Motherboard. Now with the 84V mod though, I can...

@ESM-NL I do apologize, but I'm still rather confused, perhaps because I've not read all the posts pertaining to this topic (which are mostly on the 68kMLA.) Are you saying that with the Stock CC Motherboard in combination with the LCD kit, you get only 16 colors at 640x480 (which is the only...

@Marconelly Before cutting anything, I strongly suggest you reach out to that YouTuber (video in your opening post) to tell him your experience and ask him how he was able to reassemble it without using a dremel. Because if he did use a dremel, that wasn't in his video, so he might want to...

Not that the LCD kit displays only 16 colors, but that your custom-built Analog Board, when driving the stock CC’s CRT (not the LCD) can only produce 16 colors due to its limited VRAM?

Thanks, @ESM-NL ! The LCD looks good. It does seem that it’s not displaying its native resolution though. Can you confirm?
