Alright it seems like it was a CLUT problem. Is it an issue long-term to run a bodge wire to reconnect VRAM pin 8 to the CLUT? Thoughts? Seems to work OK so far...

Here are a couple more screenshots. As mentioned the bars occasionally disappear and shimmer a little bit depending on content. The bars on color mode are almost always green, and about half the distance apart of in monochrome mode.

Would this indicate a VRAM issue after all? In Color mode the bars can vary a bit more (and somewhat disappear depending on what’s on screen), but I chalked that up to the way the system is dithering to make the different colors.

Seems like those are very close to the caps on the RAM side of the board so that makes sense. I don’t see anything that’s obvious but the recap may reveal broken traces. Thanks for the tip!

Hey another update: I was able to locally get a small VGA LCD and a couple of adapters (one is the unimac 82d-style), so why not fire it up again and see what happens? Unfortunately, I have lines on the screen no matter what dip switch settings I use, and in monochrome or color modes. I’ve heard...

I used the Mean Well RPT-60A in my LCII and it was a relatively easy swap for my TDK. I soldered the power switch/socket and motherboard harness directly to the board after removing the connectors. You could also probably find new connectors and put them on the wires, but I don't have the...

Update for anyone who cares: I gave the logic board a thorough cleaning, and replaced the PSU with the suggested Mean Well model. I wasn't sure if it would do anything at this stage, but I got fan spin and a chime! Next up is getting some help with a recap, ordering upgrades (probably from...

Thanks for the context and I get that working with stubborn creators can be frustrating (that's my day job!) but at the end of the day I'm just a moocher. Who am I to criticize anyone for their hard work and passion, even if it's work I don't like. I'll be sure to get the V2 for this machine...

What does that last part mean? It's cheap open hardware—nobody is making much money off of the project. Personally, I will always pick the option that has the best community support and transparency over something closed off. But it's a niche hobby and I think everyone contributing deserves...

Thanks all for the feedback!! It's greatly appreciated. Here's my gameplan so far: Recap logic board. I know someone who has better equipment than I can justify owning, so he'll do a great job with the hot air station. He has some other LCs and hopefully we can test the board to verify it's been...

This may be a basic question but how do the colors on the wires correspond the different rails on this PSU? I assume black is GND, but what are yellow, orange, and blue? I have this PSU but it's completely dead and I have no way to measure them right now.

Is there any way of getting a mounting panel for the DC-in jack? The Rabbit Hole kit doesn't come with it as far as I can tell, and I can't find a 3d-print file on the repo. Thanks!

Is there any recommended VGA to HDMI option on Amazon? I don't trust anything on there...too much junk and bot reviews. I think if I don't mess with the PSU and just replace it with a power brick and picoPSU that might be a little safer :) I like the way a classic CRT monitor looks but it's...

Hi there, I recently got my Mac SE in good working order and I was generously gifted an LC II at a vintage computer show yesterday. Looks like I accidentally found a new project! The logic board is not battery bombed thankfully, but the caps are showing signs of leaking and will need to be...

I'm in the US, in Seattle, Washington.
