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.

As I said at the beginning, leave the original crystal oscillator alone. It probably won't work if you remove this structurally. 1: INH, Connect this to GND to stop transmission. Leave it N/C this time. 2: GND, Connect with Spicy GND 3: VIN +5V, Connect with Spicy VIN 4: Frequency Output...

Originally it was 25MHz! sorry for the misunderstanding. It's 3:30am now, so I'll reply tomorrow. CU!

After adding the diode, It was able to shut down stably!!! Beezul-Bulb wasn't wasted! Schematics very soon!

Hi @iPhil64, To be honest, I don't have this model, so I would like you to consider it as a recommendation based on my guess (*desk theory). Please note that we cannot take responsibility even if you break it. I think that it is not the black crystal oscillator in the image that outputs to the...

This movie is cheap PSU Next is newer AcBel PSU:

I saw your circuit. Our Beezul-Bulb LED switching board made for Blue SCSI was almost the same, so I tred your method. I experimented with a cheap, unnamed switching power supply and it worked fine. I was delighted that Beezul-Bulb could be used for other purposes ... Then I used the new AcBel...

Flash for Mac from AEC-6280(PC) For ACHIP chip Remove: R16/R18/R71 Add: 102 on R71 For ACARD chip Remove: R71 Replace: 102 on R16 and R19 When I read my memo, it seems that I was using the PowerMac 8500 in striping mode at that time...lmao The procedure for passing the flasher is the same...

You'll find that you read my post carefully. Of course, when converting from a PC card to a Mac, it is necessary to move and add resistors. No need to move or add resistors when using 6880 (6860) Mac for 6280 (6260) Mac. For Beige PCI Mac Raid does not perform well due to the slow PCI speed...

Hi, You don't need to do that because your card is fast enough, but here's some overclocking information. This card was often slow, such as 233,266,300MHz, but it also has both 512K and 1M caches. Pic is my old stock, 266MHz 1M-cache. As with other accelerators, the CPU operating magnification...

Look carefully at my schematic. See that the fan is directly connected to 12V so that it is not variable. Thanks

**It has been uploaded during editing, so I will edit it, but I will fly to a place 1000km away from now on, so I will upload the pictures after returning on Monday. *Please wait for a while as we will look back at the all process again. 20 years ago, I was still active and using the PowerMac...

I noticed that the small circuit of the transistor is exactly the same as the Beezul-bulb we made earlier. I made it to control a Bi-color LED for Blue SCSI. I have just finished the 9600 test, so I will use it to test. Since it's a Power Mac lol, I will set up another post.
