Actually, you can. I know people who have safely used modern AC Adapters with their Portable but those Adapters match the Apple Adapter in terms of output being 7.5V @1.5A. Voltage and Current output must be the same, and such Adapters do exist. Tolerances of those modern Adapters (as reported...

@Fizzbinn Thank you for the links. No scary warning that I could find (yet) about AC Adapters rated for more Amps than the stock Adapters, but the search is still on for that. I see in some of the documents you linked that NiCd batteries were mentioned. I've seen people replacing those with...

The rabbit hole opens and now the heat is on the find that elusive tech note!

Actually, you need to go back to the Macintosh Portable to understand. It's not Ohm's Law. The Mac Portable's power system was really a crazy design because if you used another AC Adapter with the same voltage but higher current (even only 1A higher current output), that would fry motherboard...

I just now edited that link in my previous post, thanks. There are others like the following too: https://www.amazon.com/SRGTHE-Compatible-POWERPAX-PTD-07530V-Switching/dp/B0F93TM771/ I didn’t pick any of the voltage adjustable ones because most of those seem to require that you use an...

This thread is 4 years old, but it seems like no one has tested any AC Adapter rated above 3A out of fear that even the higher end models like the 180c lack the appropriate circuitry to handle more than 3A of current. But if a modern Adapter works well, it makes more sense to use them than the...

Exactly. And that’s why I always envisioned Sluggo to be punching Windoze (proper spelling) in the face back then. And what Power Computing was doing back in those days was no joke. They were besting Apple on the performance front and showcasing how great the Mac could be.

Wow! Love it. Where do I begin? In the first part of the video, LeVitus said he was "hot for Mac clones." Indeed, a lot of us were back in the day, even though I think most of us knew in our gut it wasn't going to work out so well for Apple. We users back then could see the negative impact...

The G4 Cube I am testing on has the stock ATI Radeon Rage 128 Pro installed. So I guess 16MB of VRAM? The machine is at the office and I’m home for the weekend so I can’t check right now.

I just downloaded the new v3.1 under OS 10.4.11 on my G4 Cube (with 1.7GHz Sonnet CPU). Disk image mounted fine. But the MacFox v3.1 app launched and crashed right away... Again, I don't know how to convey this info to the developer, but if anyone here does, please pass the word along. Thanks.

Alas, it's not yet ready for Tiger. On a G4 Cube running a fresh install of 10.4 Tiger, the disk image won't even mount... When I update to 10.4.11, the disk image mounts and I can copy the app to my HDD, but when I launch it, it crashes. Reporting it here on TD because I don't know how to...

I actually found this thread looking for the UNMODIFIED "Apple CD/DVD Driver" Extension that appears in a clean install of OS 9.2.2, but ultimately I found it. Attached is a ZIP archive of it for those who need it.

I have a flyback from an SE/30 with exactly such a broken bar. I replaced that flyback from a NOS flyback I purchased way back around 2006. Sadly, nobody makes these anymore, and it's really sad because the flyback is the SINGLE MOST NEEDED COMPONENT of any on the SE and SE/30 Analog boards...

Your Analog board was professionally recapped at the start of this thread. After some discussion, you decided to change the transistor, BU406, and you said that made a meaningful difference at the time. But today, problems seem to remain, and the consistent thing on your analog board is the...

Please let me know when the Tiger (10.4.11) version is out. My 1.3GHz 7455 G4 Cube would love to use it!

This is absolutely outstanding. You see, every single time I use my M1 Max 16" MBP to add a new disk image to the SD card of my FloppyEMU, the card gets fragmented. I've spent hours and hours trying nearly everything to prevent the fragmentation, but nothing worked. I don't have this problem...

I don’t disagree with that, but the rollers behaved 100% the same before and after my IPA cleaning. Meaning, when using my finger on either roller, the arrow pointer moved just fine on screen; but when I put the ball in, the behavior was bad, as shown in the recent video I posted in this thread.

I’ve seen the removal of the trackball assembly from the case and therefore understand how to do that, but I’ve yet to find a single photo on the tear down of that trackball assembly, which is rather interesting. Have you ever disassembled the trackball assembly? Yes, and I mentioned my having...

@Kai Robinson Before I embark upon disassembling the Trackball Assembly (a more complex job than on a Mac Portable and the reason I started this thread), is because I have no experience doing this, and I have read extensively about broken standoffs caused by merely opening the machine in the...

I checked the ball with my precision Mitsutoyo calipers just now, Kai, and it's 30.03mm in diameter nominal, deviating only by +/-0.01mm as I rolled it around and around in the calipers. Roundness is excellent. Surface is extremely smooth, with no pitting or flaws that I can detect.
