Certainly not normal… but very common. Leaking capacitors C10 through C13 cause damage to the IIci’s soft power circuit by damaging nearby traces and chips UB13, UD13, UE13. Even if you have recapped those, there could be remaining damage to the traces/chips, or there could also be cap juice...

That almost sounds like what it takes to purchase a piece of Goro's jewelry :)

I agree with everything @caver01 stated. He is spot on. I do feel that infill has to be provided as an option to the purchaser for the reasons @caver01 stated. But perhaps there is merit in having a basic novice interface and advanced one. Stuff like tapping threads and adding brass inserts are...

I would expect most mass produced parts to be injection molded. But that is too involved/expensive for hobbyists (like me) to do for small quantities. @JDW, resin is pretty strong depending on how it's cured and which resin you go with. Only issues why I don't use my resin printer often is the...

That original STL file you linked in your post, I took a look at it and it seems it was generated in Blender. I've seen a lot of great work done in Blender, but I have seen it used more for 3D modeling free form objects, figurines, artwork, something more unique, etc. Whereas for engineering...

If it’s just the bracket for the fan, wouldn’t PLA work? The temps on the bracket would be minimal and PLA would be strong enough for that application and cheaper. I have drive cases printed out of PLA which do just fine, and they get banged around more than that fan bracket will. Made a fan...

I love mine as well. Works really well and the LCD panel that @zigzagjoe selected is a gem.

I was going to ask if this was the one on sale in San Francisco a few months back on Craigslist. I was tempted but the listing was gone before I could act on it.

An SE/30 with SCC chip issues or problems on the serial circuit will fail to boot under System 7.x whereas it works fine under System 6. There’s apparently some checks that System 7 does during the boot process which will cause a hang. I hit this while fixing one of my SE/30s. I had a post on...

FWIW, four battery bombed IIci/IIcx boards sold on eBay in the past month for around $15-$25 each so certainly a good way to harvest the Apple proprietary chips.

I just found a newer thread regarding display rotation and the RGBtoHDMI project. https://github.com/hoglet67/RGBtoHDMI/issues/412 Might be a solution to provide both rotation and crop? If not, I would think that modifying that code base would be the fastest path to getting something working...

I think the SE/30, IIci, IIcx, IIsi, all used variants of or the same Apple 344S0061 swim chip?

Ah got it. Based on the name I thought you meant scaling it to fill. Cool!

Plenty of 15” 1024x768 panels. But at that resolution, do you really need a scaler? Why not 1:1 with cropping?

Not sure how you have been searching for a replacement SWIM chip, but if looking specifically for a donor from an SE/30, that could get pricey or be hard to find. It was my impression that a compatible SWIM chip can be obtained from a IIci or IIcx motherboard, and those logic boards are much...
