I absolutely HATE soldering PLCCs or other chips where the pins curl under the body AND when the PCB pads don't extend out from under the legs much at all. It took me well over 1 hour to solder a tiny PLCC chip used on one of the small PCBs that Kai R. sent to me for the SE Reloaded project...

Just wanted to follow-up to ask if (1) you completed your build and (2) if everything worked okay when finished?

Thank you for your time in answering my questions. And I hope you don't mind that I posted here instead of a private email. I thought our public back-and-forth might help other MacSD owners who are reading this thread. In answer to your question, I currently do not have CD audio from MacSD...

@YMK I installed Firmware update 2.0.2 successfully on one of my MacSD units. MacSD Commander is really neat. I love the little animated rocket icon in the upper left corner of the About box! :) I do have a question about the Preferences though. When "Transfer priority" is set to "High"...

Jeff, that's a Mobius brand SE accelerator, but maybe @BFEXTU might have some thoughts on it since it's quite similar to the SuperMac SpeedCard in design, especially with the pins coming out like that at the bottom of the card. Unlike the SpeedCard though, there is a passthru connector on top...

How high have you been able to overclock them? (Please tell me you have overclocked at least one. :) ) Also, I know that Eric Woo sells GENUINE chips, which is a huge deal. But does he also test them too to confirm proper operation? (Maybe @Mr. Fahrenheit would know.)

Thanks for the Feedback. Sorry to hear that. Do you think the problem you have now with the CRT resulted from your fiddling with those two POTs?

Holy cow, @Bolle ! That's the first I've ever seen of that SE-compatible PowerCache. That's the most unique vintage Mac accelerator I've ever seen! Super rare, to be sure! QUESTION: My SE/30 edition socketed PowerCache has no issues with audio. Does your SE edition PowerCache have issues...

@YMK In an earlier post in this thread, @Kay K.M.Mods said that PP7 changes the 5V rail and something else, but he didn't specify what else. I assume 12V too, but maybe something else also? Also note that @Mu0n wrote this 68kMLA post about voltage adjustments where he indicates that PP1...

The reason I didn't highlight the "PowerCache" in yellow in the chart I posted earlier was because it doesn't include the "SE" in the compatibility list... I have the SE/30 edition, which is a socketed accelerator board, but of course the SE has a 68000 which is a different shape. There...

Both. Wow! The 50MHz Gemini Ultra is THE fastest SE edition accelerator I can find, since no 040 accelerators were available for it. But are you saying that when using the newest drive, video is slower than stock when the accelerator is running, or are you saying that the video isn't...

PP7 changes ONLY 5V and nothing else?

@YMK It's difficult to get my scope probe to fit with the motherboard inside the case. The best I could do was use one 20cm wire between Spicy O'Clock's 5V pin to the outside of the case, connecting to my Scope Probe. I then used the GND on the external SCSI port to my Probe's GND, thinking...

I don't have a lot of time after work tonight, but I will try my best to fit my Scope probe nearer to the source, rather than use those 20cm leads. I know from experience that the longer the scope probe ground, the more pronounced the noise is on switching power supplies, especially the ESL...

@Zane Kaminski Your official posts in this thread have have been silent for the last 4 months, so I do hope there are still plans in the works to make the fabulous accelerator happen. To continue what I had said before about distorted sound, I was Googling SE accelerators yesterday and found...

@YMK On Youtube you wrote the following (see blue highlighted part)... I made time this evening to do 2 hours worth of measurements on the 5V line. I tapped 5V and GND on Spicy O'Clock because (1) it was most convenient, and (2) it taps those connections very close to the CPU. I used my...

I keep repeating that it could be a knock-off IC causing issues; but if that's true, only a swapping of the BluePill would fix it. I honestly don't know what else it could be, but I am not the developer, so my feedback is limited in its usefulness.

Other than the solder blob at C14 which isn't hurting anything, I cannot see anything wrong. I guess the white I am seeing under the main chip on the BluePill is silkscreen. Even so, I can't help but wonder if that chip being a fake instead of authentic could have something to do with it.

I'm very sorry to hear that, @Michelangelo. You have a very stubborn Analog Board!

There's not enough resolution for me to determine if there is crud between the pins or if it is just blurring and lighting... What I am forced to do whenever I use my iPhone 7 (yes, I'm poor) to shoot Macro photos is use my left hand to place a macro lens in front of the iPhone lens to shoot...
