Interesting to see tantalum caps on the motherboard, which seems to indicate power stability is less of an issue on that board than it is on the LC575 board. On the LC575 motherboard, both @Kay K.M.Mods and @Drake informed me that that couldn't overclock very high until they recapped (and in...

Texture and color matching are quite nearly perfect, Kay. Amazing craftsmanship! Two MADE IN JAPAN masterpieces!

Very interesting. On my Color Classic Mystic (LC575 motherboard) with 640x480 VGA mod, regardless of my attempts to change the display size, FPS will not display at all in Doom II. Since it displays on your CCII with the stock resolution, I am now curious as to the technical reasons why it...

For most people, the gold-toned 45x45x10mm aluminum heatsink shown in my Spicy Part II video is probably just fine. Using only 2 screws, a 40mm fan mounts well on top. You also made a wonderful 3D printable clip for it, such that decent thermal paste can be used. I'm definitely going to give...

That heatsink with embedded fan looks pretty slick, and it certainly is the lowest profile fan you can find, but with few fins compared to the 45x45x10mm gold-tone heatsink that I currently use, I wonder if the embedded fan version heatsink really offers the same amount of cooling. Fan noise...

In terms of noise, yes it will be an improvement over most 40mmx10mm fans. In terms of airflow and cooling, maybe not. Noctua keeps noise in check by selling fans with only modest RPM speeds. If you have a very noising 40mm fan in there now, I'll take a guess the RPM speed is higher than that...

Now that's pretty incredible. Amazing! 🤯

Fantastic work! I've updated the text description under my video, and I added content to my Pinned Comment as well, linking to your GITHUB page. I can also make mention of it in my next video to ensure no one overlooks it. I will also mention it in the Vintage Apple Macintosh Enthusiasts...

I don’t have an LC 475 or even schematic of one. But what I do know is that most of these aluminum electrolytic capacitors are placed between +5V and ground or +12V and ground. But if that was the case on the capacitor you say was shorted, that would mean 5 or 12 volts was shorted directly to...

Again, I am quit impressed with your work on this! So long as there are quiet 60x10mm fans out there, I don't see an issue with going with that large size. But for the record, Noctua, my quiet fan maker of choice, does not have a 10mm thick version in a 60mm size, and their 25mm would be too...

Holy cow, that thing is incredible! Bravo on a job well done! Will that be a public STL file release or an item you will sell? I'm eager to give your creation a try with my gold heatsink and some Thermal Grizzly Kryonaut! When you say "screw a 60mm onto it," do you mean a 60mm fan?

Will that clip design work with the 45x45x10mm gold heatsink?

Very interesting! @Kay K.M.Mods is quite adept with his 3D printer, and you can see the new back panel and Spicy mount he made in my video. Perhaps you two should do a joint effort on a heatsink clip! The heatsink shown in my video is a nice one, spanning the full 45mm width of the 040 chip...

Welcome to Spicy O'Clock Part II, folks! 51.6MHz, anyone? :)

I actually mention my hope someone could design a "clip" on my Part II video on Spicy. I too want a solution that allows me to use a high quality thermal paste, rather than thermal tape, to yield the best cooling. Of course, it becomes a little more complex when you also want to tack on a...

Indeed, and I never said MLCC's "can't be used at all." As to the other technical information you kindly researched and linked for us, I appreciate that very much and think it is good reading for those who are less informed about the caps we are talking about. At this point, I would recommend...

Ceramic caps are unfortunately a BAD idea for reasons I will now explain. Unless you use tiny capacitance values in the pF or nF range, such that you can actually use NP0/C0G types, you would need to use an MLCC like an X7R. NP0/C0G caps don't have a voltage derating, which is great. But...

I would suggest you halt everything until you've recapped, and my advice is to use OS-CON or similar solid polymer capacitors with super low ESR to make 100% sure the craziness you are seeing is in no way whatsoever related to voltage instability on the motherboard, which likely is the case if...

I can only say that those test results don't follow what I've been seeing in my 4 months of testing on the LC575 motherboard, so we really, really need another LC475 user who also has Spicy O'Clock to explain in detail what happens on their machine, at the same clock frequencies you used, and...

I have access to 2 scopes at the office, both 100MHz only. I also have a logic analyzer, but it too maxes out at 100MHz, and only for 2 channels. @Zane Kaminski You do a lot of design and testing work. What reasonably priced 500MHz scope would you recommend for general use? Being able to read...
