Although this schematic set only covers the non-backlit 5120, much is similar to the 5126. For example, the audio section matches my 5126 Portable quite well. The Hybrid section is of course different. To download, click the blue button in the upper right corner.

Now as to SunBright or whatever the H202-free method is called, I tried it after seeing Perifractic try it on his Retro Recipes YouTube channel. It did not yield great results for me, and on my HD20 enclosure, I was hard pressed to see any improvement at all, even after 4 days in direct sun...

Please don't take this as a chastisement of any sort, but I feel strongly that we need to mention the CONCENTRATION of H202 whenever we talk about it. If people are referring to that 40% stuff, then yeah. But if we're talking about the 3% drug store that even I can buy here in highly...

Sorry for replying to an old post, but I've not posted in this thread in a long while and I only finished reading all the pages of this thread today. I wanted to point out that "rkauer" stated that he is using "a flask of 40% H2O2." Forty percent is an extreme concentration that I cannot buy...

Would love to hear your opinion on bakinghe LCDs. (I just finished reading all 15 pages of that monolithic thread, by the way.) I have baked the graphics card inside the late 2009 iMac because those have no electrolytic capacitors on them. But a graphics card isn't as fragile as an LCD...

Thanks, Kai. Hmmm... Setting the oven to 85°C isn't too bad, but 9 hours! His before/after looks promising, and I see a comment made under his video several months ago asking how the LCD is today, and he replied it is the same. Of course, his PB170 LCD type isn't 100% the same on the...

By the way, I didn't notice it at first because I only received my 5126 Backlit Portable a couple days ago, but the lower left corner very slightly darkens after a few minutes of the machine being on. It seems that is called tunnel vision. Supposedly it is moisture that has gotten inside the...

I spoke with @Sideburn privately. USPS are real stinkers, wanting $19 to ship something super tiny and feather light to Japan. So I did a lot of searching and found clear 0.8mm x 4.0mm silicone tubes in 1 meter lengths for $1.17 + $2.56 in shipping to Japan. (They offer free shipping, but that...

I was hoping to just buy using your EBAY link, but despite the seller being in China, they refuse to ship to their next door neighbor! What the...!? I will send you a PM shortly.

Now that I have a 5126 Portable, I am finding my trackball to sometimes work and other times not, the culprit being those nasty Rubber Rollers. Using my Mitsutoyo Digital Calipers, I measured the following: 1. Metal Shaft Diameter: 1.0mm 2. Rubber Roller Thickness: 3mm 3. Rubber Roller...

NOTE! The motherboard has been ultrasonic cleaned, recapped, traces repaired, and cleaned again via ultrasonic. The Apple AC Power Adapter I am using has also been cleaned, recapped, and cleaned again. PROBLEM: I'm hearing a soft pop sound from the speaker every 10 seconds when my 5126 Backlit...

I will connect the spinner drive to get that data point. Thank you for all your kind help to date!

In my conversations with @eric regarding BlueSCSIv2, he recommended that I completely disconnect both power and the SCSI cable from my spinner drive so my testing could focus specifically on the SD card drive in question. So I have been testing MacSD separately but in the same way as BSv2...

@YMK I've also been talking to @eric via PM, and he asked me to install Macsbug and then enter the debugger by pressing CMD & PowerKey at the time of the lockup. When I do that, I see the following (two different screenshots because I tried it multiple times): To escape out of the...

I am seeing some incorrect info posted on the internet when it comes to ADB pin-outs, but it would appear the following should be correct (I think) when looking at the back of the LC575 motherboard. When I touched my multi-meter's Black/GND probe to one of the motherboard connector bolt...

The "no peripherals attached" part is problematic because you need an ADB keyboard in order to press the PowerKey and power-on the Color Classic Mystic. And removal of ADB devices while the machine is powered is not advised. When I have disconnected an ADB device in the past by accident, it...

Yes, but such is nothing new. The same is true when I try to boot from BlueSCSIv2. Pressing SHIFT allows it to boot to the Desktop. But it cannot be an extensions conflict, for two reasons: 1. I can boot my spinning platter drive just fine without pressing SHIFT. 2. I've spend hours...

@YMK Here's a video showing MacSD LEDs during booting into 7.6.1 at 43.2MHz (no lockup) and then at 48MHz (lockup):

I cannot answer that question until I test again, which won't be until late tonight after work. Thursdays are my late nights when I don't get home until past 10pm. Yes. As discussed in my earlier post, SCSI_Clk attaches to CK on the 53C96 SCSI controller chip, and SCSI_Clk is feed by Q_DIV_2...

Since I mentioned MacSD and BlueSCSIv2 in my previous post (posted 10 days ago) and received no reply until today, I will tag @YMK and @eric so as to glean their thoughts, even if it is speculation. (I'm speaking to Eric outside this thread about it now.) SUMMARY: With MacSD or BlueSCSIv2, my...
