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.

Power Mac 9600 has joined my team. The Mac I longed for when I was young. Apple has bestowed the glory of just 3 months.

In addition to the TDA7052A, the LM3080N was also commonly used as a power amplifier of this generation. In the case of TDA7052A, it is hard to say that it is limited to 8Ω. There are 8Ω and 16Ω speakers, but it seems that they are selecting the right number of ohms according to the power output.

Thank you guys. @winters It's enough if you understand about half! Seventeen years ago, people around me used this SE/30 as a normal Mac, but no one cares about the contents because it works properly but it is old. @joshc that's right. My focus was on the craftsmanship of manufacturing. What I...

This photo is from a magazine(iPhone's screenshot). The story and restore of me and my Porsche was featured using 10 pages. It was a Japanese Porsche magazine. @pocketscience , Your hobbies are looks like mine lol

I bought this at a Yahoo auction in Japan, but it was quite expensive. When this is stabbed, it becomes Simashimac (a composite pattern that adds horizontal stripes instead of the usual vertical stripe pattern). Here's what I did: -The ROM was replaced by flashing 4.1.1 and 4.0.1. -Cleaned...

No worry James, Now I have Satanic SE/30:ROFLMAO: The Turbo 040 I bought the other day is also broken, and any further investment in the SE/30 seems wasteful. Instead, I would like to support Zane's project👍 It's completely different from other clones. If there is a pre-sale, I will buy it, and...

This is only vintage Mac world for me, but I post few pix before. Return to the T-shirt topic, we'll make a 3XL, XXL, XL in the near future!
