Satanic Mac Club!

How about this...

One very sure way is to remove the Pot first. Measure the resistance with a multimeter while turning the pot. It is better to measure terminals 3 to 2. When normal, it can be varied linearly. If the carbon is frayed, you will see ohm disturbances. For example, a point of several milliohms...

As I said many times, it cannot be used where the carbon is worn away. or scratched. Useful for surface oxidation. My company has been a distributor of CTS for 20 years. Trust me!

Look at the actual structure. The resistance value is determined by moving the brass terminal back and forth between the resistance band made of carbon. This is the same for the big 24mm Pots and this little variable resistor. If dirt due to aging is the cause, the contact restorer like DeOxit...

I think it comes with the fact that you're from Mars😂 You can arrange the buttons as you like, so I think you should make it with your favorite arrangement. I hope I can help you finish making it BTW…🤘

If you've ever played an arcade game, you'll notice that firing with your right hand actually makes more sense and has a higher success rate. It was from Space Invaders that people realized that. The Apple joystick has a left-hand button due to its older design, which is unsuitable for long...

Congratulations @eric . JDW told me you finished this. But I found an embarrassing spelling mistake in my schematic🤣 I'm thinking of making this easier now. Excellent STL file and BOM list. I need some time. Also, Apple's stock joystick has an interesting structure, it goes from 0 to 255, but...

if it works fine... You should remove the tube and keep the 5v line and clock line from sticking together. It is preferable that the GND line is in between them. I think you can overclock up to 42MHz even with tantalum capacitors.

Hi @SadMac , If I had to give a little advice, first, there are a lot of exposed parts at the ends of the lines, so make them a little shorter. And a lot of solder. I can't see the wiring of the XC88916 very well, but please confirm that the 8 pin is definitely floating from the footprint and...

Hahaha Nice🤣

Thanks James! In his video, I could feel his respect for me and @JDW and @Stephen . Of course, you who are YouTubers are always aware that the contents of your videos are independent and original. So you should always strive to be exciting in order to surprise others, you could do it too I...

The problem seems to have been solved without me having to answer. I'm sure he is the best SE/30 repairer in Japan. He has a lot of skills and his website has a lot of hack ideas. I exchanged emails with him twice. I don't think there is any possibility that I will handle his product at this...

PPC card and Spicy O'Clock!

Thanks, 500W is usually sufficient. In fact, if the capacity is large, the heat generation is also large🥵 I just used what I already have...Please choose the PSU that is convenient for you!

Satanic Mac Club's previous product, the Beezul-Bulb, is now available as a generic Mac softswitch for PSUs. PowerMac 9600 wiring can also be analyzed and tested on my 9600. We sell rewire and bracket kits for this. https://ameblo.jp/keroxiee1016/entry-12756425050.html...

A sine wave is different from a jagged waveform like a crystal oscillator. Even so, it becomes slightly unstable around 30MHz, which is the upper limit of this variable oscillator used for Spicy. However, since it is designed exclusively for the 68040, the upper limit of Spicy itself is 26MHz...

In the case of Quadra650, when the tantalum capacitor was replaced with OS-CON, there was a clock difference of 5MHz. Very effective.

Hey @iPhil64 I've been thinking what you are trying to do with the Quadra660AV, I searched a lot but could not find useful information about Overclocking. One thing I learned is that the crystal oscillator replacement is limited to 17.4Mhz, which means that the CPU clock is limited to 35MHz...

Sorry for not being helpful, but I will get same Mac if I have a chance.
