This video I introduce my iMac based Late 2004 G5 Power Macs and build one to use... I also transfer the Jive into it in the video

"Don't scream! Don't scream!" lololololSo I dedicated most of this month on my channel to the PPCChallenge upgrading systems and testing weird stuff. Here's the first video on the Sonnet G5 Jive
Yeah just IPA bad suggestion... white vinegar to neutralize it then IPA to remove the vinegar.... figured that out here:Day 15
G5 Dual revisit
So i have the dead water cooled 2.5GHz G5 dual, and an air cooled 1.8GHz G5 dual. I got a replacement power supply from eBay for the liquid cooled Dual G5 2.5GHz, but it still showed no signs of life, then discovered the coolant leak. Hence the FreeGeek salvage 1.8 dual was purchased as a boot problem project. I found out the 1.8 dual had mismatched processors, so... following the guidance of @HrutkayMods in this video, I converted the Dual 2.5 water cooled to air cooled.
Cleaned all the residue I could find off the 2.5 motherboards and put the air coolers from the 1.8 onto them. This is my bath of IPA 91% and toothbrush action residue.

So, to start, I tried the 2.5s in the 1.8 motherboard (with the assumed solder flex issue) and it powered up but no chime. I then tried the 1.8s in the 2.5 dead motherboard and it actually powered on with no chime. First life in that motherboard detected, so put the air cooled 2.5s back in the original 2.5 motherboard, and it gave me an abruptly cutoff chime, no video. Reading some other forums, they said to let it run for 10 minutes and then restart.... bingo! The video card came to life and I was able to boot off my external rugged LaCie Firewire drive.

Once booted, I confirmed both processors were actually detected.

Then I pushed its limit by trying Xbench. Somewhere in the middle of the graphics 3D OpenGL test the machine went completely silent. I thought it had died, but in fact it just went into power save mode? The front panel power light was still white, so I pressed it to turn it off and it came back to life, right back in the middle of the graphics test. Xbench completed and I was able to screen shot a comparison.

I pushed my luck by trying to select a different boot volume (10.5.8) and restarted with no video again. So, there is life, but its very inconsistent at this point. I am wondering if the performance test did a thermal shutdown because the water cooler pump is not attached? More testing to come.
In my experience once they do thermal shutdowns like that the cards are usually pretty toasted. If the cards were not cleaned perfectly the first time around, they just start calming apart with heat cycles and shorting and stuff. I would look over the both cards as closely as I could. It may do another IPA on them and let them sit overnight to make sure they’re extra dry. There’s a chance everything still salvageable if anything the CPUs just may not be seated properly. In fact, try to push down on the heat, sinks and see if it comes on. If not, I’d also check the sockets and make sure there’s no bent pins.Day 16
G5 Dual 2.5 rebuild
I tried to do some more benchmarks, but it keeps going into thermal sleep, after 10-15 seconds.

I aborted the Cinebench test, and downloaded ASD 2.5.8 and burned the CD. I could not get it to boot into Open FIrmware, but the OS version booted. Of course the CPU tests kept going into thermal sleep, so I would wake it up every now and then, hoping some cool off time would keep it running longer. It still took almost 90 minutes to get the "Passed" green.

I figured what could it hurt to completely disassemble it again, redo the thermal paste on the back of the motherboard, dowse the CPU cards in white vinegar a la @HrutkayMods and then rinse with IPA 91%. After a thorough dry time in front of fans, I reassembled everything. Powered on nice and quiet, no chime. One red light under one cpu. So waiting 10 minutes for it to warm up, then will try another restart.
I have tried to threaten by cursing in as many foreign languages as possible, but if it won't comply... Goodbye Johnny-Five.
Do I get my shout out for fixing your overheating issue in the other video?Releasing in two hours (from the time of posting). A nice video on how to get ProtoWeb and WarpStream working on your PPC Mac
Nice, I'm a heavy ProtoWeb user but I had never heard of WarpStream until now!A nice video on how to get ProtoWeb and WarpStream working on your PPC Mac
NOOOOO! As soon as I saw Action Retro's post I was gonna take out the G4 MDD and install it (tried to install last year, didn't work) but maybe some TechTuber will come out with a new guide on how to install.Sadly the installer is still broken.
There's another emulator, that Apple produced back in the early PPC days. Gus 1.0b4. Emulates a ROM 3 IIgs. Even runs the IIgs self-test routine, obviously saying "System Failed" at the end, since the hardware isn't recognized by it.Day 20: Reminisce the old days
A few years back someone was cleaning out their storage and happened upon an Apple IIe and IIc, and gave them to me. I had to buy the power supply for the IIc from eBay, and disassembled them both before powering them on. I had some old floppy disks from the 1980s in High School, so I found the wiring diagram and ADTPro to transfer them to my modern mac. I haven't thought of those in years...
So for the PPC Challenge, I looked around for Apple II emulators... sure there is nice web based one where you can play online, but I wanted a PPC native one. Virtual][ is a pretty good emulator, but their website is focused on the present and they don't have an old PPC version there. I did find one on the Way Back Machine for PPC labeled v5.8.5, and it does load, but extremely slowly to boot the first time. Running on my Mac Mini G4 1.42GHz. (I see v3.5.1 is on Macintosh Repository, but the website appears to be migrating: "Sorry, we're currently migrating files in to the new server. Most files will be available around January 21st, 2024.")
Once running, I loaded up some old disk images and had a look around.
A program I wrote with a high school history teacher, called "Badger Bits & Bytes" was a trivia game based on Wisconsin history (almost 40 years ago).

Cavern Lander was my take on Moon Lander written in Apple Basic (ProDos 3?)
View attachment 14716
It worked in mono or color

And for some reason I seemed to have some early Pr0n disks... Strip Poker and something called a "Santa disk"
