QUESTION #1: As per the above, did you ever check that the 9V battery works properly? QUESTION #2: So when there is no lead acid main battery in the machine at all, that 9V battery would be keeping the 5.2V rail "powered all the time"? (The same would be true if the AC Adapter cord was yanked...

Joe, thank you. As far as the Radius Rocket with RocketWARE is concerned, it boils down to this... Compatibility: The Rocket hates sound.* The system tricks it uses to run make handling sounds a pain (if not impossible). Do not install Sound Manager 3.0 or later! It can handle SM 2.0 for some...

I did a search on Macintosh Garden for "microbug" but it yielded no results. If you meant to say "MacsBug" then please let me know what version I should use under System 6.0.7 and higher. I will then boot with your recommended version of MacsBug and give your command line and noise-check a...

I use the DIP settings below on my UniMacFly adapter with my Mac IIci, either with onboard video or the Radius Thunder 24/GT. That allows the attached VGA LCD to display 640x480 just fine, and I can switch to higher resolutions with ease too, all without changing the DIP SW settings. It's...

Regarding "Sound Manager 2.0" which is RocketWARE compatible, I found the following info today... The Sound Manager was first introduced in system software version 6.0 and has been significantly enhanced since that time. Prior to system software version 6.0, applications could create sounds...

Thanks. I also just confirmed that the RadiusWare 1.5.1 Patcher is found inside Download #1 on Macintosh Garden here: https://macintoshgarden.org/apps/radius-rocket-software I also updated that Macintosh Garden page with more info to credit you, Joe, and to make it clear the 1.5.1 patcher can...

Sorry, but I can't find a link. What is the download link on Macintosh Garden? Remember, this is Tinker Different, not one of those other forums. Here, freedom reigns. Especially so because I created this thread. Besides, logic dictates that all of your posts are on topic insofar as they...

Thank you for providing those details. What I can say for now is that I have installed System 7.1 and Update 3.0, but I disabled the Sound Manager extension and I restored version 8.0 of the sound control panel. But I also confirmed that even if I use version 8.01 of the sound control panel, it...

Some truly helpful info. Thank you, Joe! If I clean install 7.1 or 7.1.1 Pro, it includes Sound control panel version 8.0, but no Sound Manager extension at all. You are basically telling me that means I have Sound Manager 2.0, hidden somewhere like inside the System file. Correct? But the if...

Still have no idea where to find the Rocket-compatible Sound Manger version 2.0, so if any of you do, please don't hold back. Separately from that... I found the RAM buffer (and Parity checker) ICs get hotter than the CPU on the Rocket. Datasheet...

I do, but the cost for me to mail it to you within Japan is probably not much cheaper than if you were to buy it from AliExpress like I did. Shipping was surprisingly quick too. https://www.aliexpress.com/item/1005001917803982.html I won't be able to mail anything until Monday anyway because...

@David Cook I didn't get much testing done this evening because I burned through all my testing time trying to get my scope to cooperate. Worked fine with the function generator earlier today, but with the actual Mac Portable motherboard readings, it's different. The actual motherboard...

@ScutBoy I found your Dec. 2020 post on the MLA, where you reported noise coming from your headphone jack. You said it was low priority for you, so I will assume you never tried to diagnose the noise. Even so, I'd appreciate knowing if the noise you hear from your headphone jack is similar or...

I have achieved success in setting up my scope as per your direction, which you can see in my video here: You are seeing my function generator's output on the scope display. My function generator was set to a 3.23kHz SINEWAVE with DC offset. Both scope probes were connected together and to...

The final conclusion of my earlier post is: TRACKBALL REPAIR SUCCESS! The tubing I ordered from this AliExpress seller ("ID 0.8mm OD 4mm") arrived last night, which enabled me to finish the repair today: I tried all kinds of nippers and other tools, but in the end, what make the straightest...

CORRECTION: The suggestion to measure "pin 12" of UB15B and UB15C was incorrect. Pin 12 is SONY_+12. The pins I need to probe with my scope are 11, shown in yellow below.

Not sure about being tricked, but the two probes are indeed set to 10X, and the scope setting for each probe is also set to 10X. There is no mistake about that. With that said, I often use 1X when I measure very small signals. For example, if I want to measure ripple riding on the 5V output of...

@David Cook One of the reasons I make detailed videos is because I am often in need of detailed help. I try to help people the way my feeble brain needs to be helped. You are providing kind of excellent help, step-by-step. It's crystal clear. Thank you! Admittedly, I've not had the need to...
