Radius Rocket is now in the house. The Rocket Q&A and this page on LEM say the Rocket works only with Sound Manager 2.0, not Sound Manager 3.0. In what download can I find Sound Manager 2.0?

The speaker is mono while headphones are stereo. The speaker also attenuates noise more than headphones. For those two reasons, I cannot hear all that noise as easily through the mono speaker as I can through headphones. With that said, I can hear that pop sound every 10 seconds from the mono...

Let’s assume for the moment that it is, as you say, the “LCD driver.“ What then must I do?

Quick question... The VGA adapter product page says this: * Please only connect or disconnect this adapter when the Portable is turned off I assume the above means the following? * Please only connect or disconnect this adapter when the Portable is Shutdown or disconnected from power, not...

@Androda , thank you for your kind feedback. I appreciate the insight. The video below shows what activates the soft pop every 10 seconds — merely booting! You can also hear how the noise changes, even when you open or close a window while at the Desktop. It would be greatly appreciated...

Okay, I did a little testing on my lunch break today. By the way, the no-load (disconnected) voltage level of my fully recapped Macintosh Portable AC Adapter measures 7.568 V. I used that Adapter to power the Battery Eliminator card. Not sure what the normal output voltage of that Adapter is...

Actually, it they won't be after him because of this... No Apple logo means the EBAY sharks will continue to sell their Apple logo branded LISA mice for hundreds of crazy dollars. But even without the Apple logo, I personally think it's awesome that Stephen recreated this hard-to-find item...

Okay, friends, here are the results of my first HEADLESS test of my 5126 Portable: Everything was disconnected from the Motherboard except: (1) Keyboard (required for power-on) (2) Battery Eliminator from Androda (3) SONY PCM-D100 Audio Recorder with headphones attached. High quality audio...

I can't sing the praises of @OneGeekArmy enough. This app is truly incredible. It's the gift that keeps on giving! Folks, if you'd like to contribute to Jean-Michel and tell him in the most convincing way possible to "keep up the great work," please note he has a Ko-Fi donation page where you...

FANTASTIC work, @Stephen ! Now I just need a LISA! 😅

According to @SuperSVGA in his post here, he says pads marked 3 & 2 for the missing MOSFET Q5 on the 5126 backlit Portable are connected together. In other words, that would mean the following should be true... NOTE: I don't yet know if the SOUND_CS circuit above is just left floating due to...

Thank you for your kindness in doing that audio testing. That confirms my suspicions. For truly, the base noise floor with the volume turn to 0 is unusually high, and such as not there on any of my other message Macs. Nevertheless, the audio works and is quite loud at the maximum volume setting...

The more I look at R62 & R63, The more inclined I am to believe that somebody must have swapped them out in the past. For example, look at the solder on either side of those two resistors in the photo in my earlier post. It comes up in the shape of a little mountain, just as if it would if your...

Honestly, I strongly recommend you purchase the following product, which eliminates the need for a battery entirely: https://androda.work/product/macintosh-portable-battery-eliminator/ I also strongly recommend that everyone recap the Portable’sAC adapter too, because all of them have leaked...

By the way, the following is a close-up photo of the two 10-ohm resistors The resistors look fine, but take note of how the 2 traces that connect those resistors in parallel have been blackened. I’ve highlighted those connections in yellow below: I was able to use an X-Acto knife to very...

Thank you for making time to reply and for confirming that the source & drain on that P-channel MOSFET are connected together on the 5126 Portable. In answer to your question, my first steps will be to test the sound with my 5126 Portable in the headless condition as shown in the photo in my...

When you test, please note: 1. I cannot hear the soft "pop" at all if the Volume is set to 0 via Control Panel. 2. I can still hear background noise through headphones even if Volume is set to 0. 3. You need to listen for 30 seconds to see if the noise changes. In my case, it does. There's a...

I wish to humbly thank you and praise you for being the first person who has so kind take time to do a listening test on your 5120 Portable. You have confirmed there is no soft "pop" sound every 10 seconds. I suspect that is true on the 5126 Portable as well, but I would appreciate feedback...

It never ceases to amaze me what determined, brilliant people can put together in this hobby. Bravo, @max1zzz ! 👏

I will admit I am disappointed that although this thread has been read 78 times, I am the only person thus far who has replied. But maybe this reply of mine will bump this thread into view and generate a little feedback from some of you. 🤞 I'm getting replies on FaceBook (Vintage Apple...
