Alright, LeopardAssist III Release Candidate 2 is now available. http://leopardassist.sourceforge.net (SourceForge, 3.1MB ZIP) https://www.macupdate.com/app/mac/26562/leopardassist (MacUpdate mirror) It has some extensive under-the-hood changes from v3.0-preview (RC1). So many that It could...

Just had the chance to listen to the attached MP3. Definitely not the Floppy Drive, but similar to the sound my 512Ke was making with the Floppy Drive disconnected. Mine is a 220v version of the Analog Board, so the component layout is a little different and the solder joints on the Flyback may...

My Macintosh 512Ke did exactly the same thing. The Plus uses the same Analog Board, so it's relevant here too. No Video / Loss of Video on Display "Flup", "Whup" or "Blip" noise from inside machine First of all, I think you'll find that the noise is from the Floppy Drive, as it attempts to...

It took a few days for the smell to completely clear out of the room. The machine still smells like it somewhat. What makes matters worse is that the capacitor leaked everywhere, both inside and outside the power supply. After moving the machine following the smokeshow, I found it had made its...

Cheers Techknight - I'll see what I find. The iMac is easy, I'll just run a couple of commands and grab the panel data, but the somewhat dead Studio Display will be a little more fun. Under Dog, I'm actually running iTunes 9 on OS X Leopard. I know it doesn't sound that fantastic, but since it...

My iBook G4 did something very similar for a long time. You may wish to take a look at this page: http://www.xlr8yourmac.com/tips/ibookg4_vreg_repair/ibookg4_vreg_repair.html In a nutshell, the solder joint fractures on one leg of that chip, causing anomalies with the system such as random...

I've recently turned my iMac G4 (15-inch USB 2.0) into a sweet little stereo system, streaming internet radio stations down and playing it back through Apple's Pro Speakers. The entire thing is controlled from my iPhone as a remote. It's pretty sweet. I can't help but notice though that its...

It's more like "I've removed the restrictions". While I was adding some new properties to LeopardAssist, I added one called "Frequency". If the frequency property is disabled for any reason, it will skip the Clock Frequency step. One side effect is that instead of having LeopardAssist fail...

For the 68kMLA. Here's the latest compile of LeopardAssist 3 (Release Candidate 2) for testing. https://app.box.com/s/pc9cubid70edtgrmw4dj I've successfully tested it on my iMac G4, however some changes that need particular attention: LeopardAssist should now throw an error when being run on...

I didn't expect Jaguar to work. It sounds like there's two issues in play here, firstly the script isn't writing correctly, possibly due to limitations with the command line tools that LeopardAssist depends on (grep, head, machine, nvram, sed, sudo, sysctl, system_profiler, tr, whoami) or the...

LeopardAssist III is almost ready to be released in its final form. At the moment the code remains mostly the same, differing only with one small UI change, new documentation and a small tweak to the debugging code (which only matters when being run in Debug mode and doesn't get compiled into...

I can confirm a moderately successful boot on my iMac G4 (15-inch USB 2.0). As expected, the video is limited to 256 colours, there's no sound and no AirPort wireless. I'm running OS 9.2.2 with Mac OS ROM 10.2.1. I've tried applying the Apple nVidia Driver Update with no change. So while it...

The iMac (17-inch Flat Panel) from 2002 is listed as an OS 9 compatible machine, and that has a GeForce4 MX in it. That particular version used the Mac OS ROM v9.5.1 which I also have. The difference appears to be that the later iMac G4s use DDR for the video memory where as the earlier ones...

I'm very pleased to report that it appears we have some success here! :D CC_333 tested the above modifications in an attempt to boot OS 9 on an OS X-only Mac - in this case an iMac G4 - and had some positive news to report: With the ROM modification, OS 9 was able to start up on this...

The machine I used to document for this thread was parted out a couple of years ago, but it took me a while to get around to writing up the findings. The case eventually went to a case modder who then turned it into a Core i7 thing. Of course, before anyone starts removing their Logic Board for...

Excellent to know! I'll make sure to update the Read Me for the final release to include a line about ensuring you have the most up-to-date firmware. :D

I'd like to introduce you to my iBook. It was from a school, and needed a lot of attention. I rebuilt it last year. It's a nice little machine, and I have often thought about using it as a distraction free machine for my writing. It's a first generation iBook G4 (PowerBook6,3) with an 800MHz G4...

Wouldn't mind having a look at that schematic, actually. PM sent.

With previous versions, I used to keep track of machines that LeopardAssist was confirmed to work on. I've since come to accept that it's less clear cut, and some machines work while others don't. So the "Known Compatible" list has been scrapped. However I have tested LeopardAssist on the...

Several years ago, I owned a Power Macintosh G5, a 1.8GHz Single Processor. The machine was a first generation, codenamed "Omega" and manufactured some time between June 2003 and June 2004. When I acquired it, the machine would power on without a chime, and the LED on the front would flash 3...
