So this is my first #Marchintosh since I get into vintage Macs. I made my first ever YouTube video of me trying to clean the rust of an SE/30 case and it doesn’t fully go according to plan

Ron, that was a great video. Good work.

I would be interested in the setup.

Thanks for the help. I am really new at this and it is really hard

So on the back of the board all I see are pins 1, 3 and 4 being used:

Ok so I can leave them off without issue. I am still wondering about the rest of the pins. I only have pins 1, 2, and 3 connected on U2. Is that all the connections on that chip?

So this is what I currently have based upon the photos. I am just wondering if I have missed anything.

Yep

@KennyPowers I have been working on recreating the board. Could you please tone out the pads next to U1 and U2? It looks like they might be going somewhere

Sorry for the clickbait like title but over on hackaday someone reversed engineered System 7 to x86 https://hackaday.com/2025/09/29/macintosh-system-7-ported-to-x86-with-llm-help/Macintosh System 7 Ported To X86 With LLM Help | Hackaday Files are open source

Thanks for those. I will see if those work. I am still very new at circuit board layout.

I also bid on that eBay auction, for the exact same reason, to get that riser. I was hoping to make a schematic of the board to clone it. Nice to know that there isn't any logic. If you could take some very high resolution photos of the riser it would be very helpful.

I really enjoyed your video. I am currently gathering the components to also do the 84v mod. I wonder if a ROM hack would be able to give the option for the different resolutions.

So when I got my CC the seller also had an untested CC2 motherboard. So I have both. I want to get it running with the known good board before I start messing with the untested board. I am looking for an LC575 board but that is more of a down the road acquisition.

I am waiting with baited breath for your video @JDW I have greatly enjoyed all of your videos so far. I have recently acquired a CC and the main motherboard has been recapped it still does not boot. I am looking forward for your video so I can recap the analog board and then do the 84v conversion
