I install them exclusively in my SE and SE/30 machines, so I’m well aware of their low noise benefits. But I’ve never installed four in the same machine, hence my question. Furthermore, except for the noise of the hard drive, those CRT iMacs are pretty silent, and therefore, you would more...

So because the motherboard remains powered, any software that can remain running while also keeping the screen 100% black could benefit from this, right? Few will probably use an SE or SE/30 as a server, but I'm just curious if that is one example use case that may see a nice...

Fantastic idea! QUESTIONS: 1. If I open Photoshop 1.0, 4.0, etc., create a 100% black screen and display that full screen for more than 3 seconds, does your device kill the Analog Board? 2. How long (approximately) does it take for the sweep circuitry to stabilize? What's the typical "wake...

How loud are those four fans going at once, and are you using the LNA to reduce RPMs and noise?

Mine was especially warm on the right side, due to the hot degaussing component there. But even though I couldn’t feel the same level of heat on the left side, I can only imagine how hot that DL22 diode was getting.

Beyond the novelty of having an Amber CRT inside a compact Mac, how do you folks like them? Would you describe the picture as being "easier on the eyes" or "just different"?

I'm posting back in this thread today not only to give @phipli praise once again for his incredible work on the 475 Overclock software solution 👏, but I also want to update all of you 475 Overclock users about the impressive work forum member @frontein1 has done (and continues to do) in boosting...

We've already talked about RAM and VRAM in this thread, but I am replying back again today to say you (and one with an LC575 motherboard) should buy not only 60ns VRAM, but also a 60ns or faster RAM SIMM too because of the incredible work @frontein1 has accomplished today...

Holy cow! All the numbers are improved across the board! I'm going to tag @YMK because he is the creator of Synchr030/S which is an accelerated PDS RAM card for the SE/30. I'm also going to tag @Willj and @Jockelill who I know are following your incredible work.

Here you are...

I'm still hoping and praying that @MacEffects can one day clone them for us. Until then, I sadly have no technical specs to provide and don't think cloning one will be possible. Most people ask about outrageously priced flyback on EBAY which are not running $145 or higher. And to think, those...

Can't believe it. Just got home from work and was able to test my Mystic when I realized that I forgot to flip off the power SW at back last night. The power was on all day in my room at home with no A/C in the heat of summer, and that means the ambient room temperature was probably 35°C or...

I'm still concerned about the 133.9°C max. temperature I measured on the 1N5355B 18V 5W Zener diode (DO-15 package size) soldered to DL22 pads. It stays that way for about a half hour after you do a Shutdown from the booted condition and then it remains at about 121°C to 125°C (well, at least...

@iantm I tagged Ron in hope's he'd provide details, but since he hasn't I can only tell you what I know, which is limited because I have a different adapter and not Ron & Joe's. You can find Ron's video adapter creations on Joe's website here...
