Another strange Power Mac G5 behavior

This one is perplexing, I have a Dual 2.5 that runs perfectly fine except when running ASD the fans will go off and then it shuts down, all tests pass, the memory test (second one) starts the fans then shut down, also if I leave it idle in ASD the fans will eventually go off and the it shuts down.
I have checked the memory with Remember with no problems.
Thermal calibration also passed fine when I finished building the machine, Im afraid now if I try it again it will crash and then I wont be able to calibrate any further.
Strange behavior, typical for a G5 PM I suppose.

I found what the problem was!
It was the CPU B's exhaust fan, It had lost it's tachometer sense so it went off into jet plane mode, ASD showed that it wasn't even there, even thought it was running as fast as it's little windings could spin it.
When I swapped the fan with another one, all is good now, the G5 will now run ASD's test's infinitely.
Apparently ASD will freak out when a fan goes AWOL and after a set time will automatically shut down, would be nice for an error log in ASD.

See and copy files from a Power Mac without keyboard and monitor

A friend gave me his G4 Power Mac. I think it is a Quicksilver. (I will post some pics of both the front and back on Flickr if anyone wants to see it.) I didn't get the keyboard or monitor cuz I forgot I would need the keyboard to use Firewire Target Disc mode on it. I just need to see what files are on it (and probably copy whatever ones I need onto my newer Powerbook.)
I have a 17" Powerbook G4 DL and a Powerbook Firewire (500mhz, running OS 9.2.2), and another G4 Power Mac ADP set up to always start up in Firewire Target Mode so I can use it like an external drive (which I never do...) and a bunch of older Macs (LC 580, SE...)
How can I get onto this new machine? I need to see what files are on there. I do not have access to another monitor but I might be able to borrow a USB keyboard so I can start it up in Target Mode. Is there anything I can do before I scrounge for a USB keyboard?
I have tried connecting by Firewire and ethernet with both Powerbooks. The Power Mac isn't showing up either way. I am pretty sure it has a CD drive but pushing on the door (one of two on the front) doesn't open it up.
I am assuming the Power Mac is running OSX.
Many thanks.
Cheers,

I think it is a Quicksilver
It may be easier to look at the rear panel for some labeling. It may be silk-screened on with white paint and a bit hard to see.A four-digit model number with "M" as a leader will pretty much nail down the model without taking photos that may not show much.Quicksilvers can have models number M8360, M8493, or M8493 depending on the config.
For snopping the drive, it may be easier to pull the drive from the G4 and use one of these extremely handy gadgets:
http://eshop.macsales.com/item/Newer%20Technology/U2NV2SPATA/
to mount the bare G4 drive on your working PowerBook with OSX. It will show up on the PB as an external drive and you can see what's there. The adaptor will be serviceable for more than just checking this hard drive. Anyone with multiple Macs will get a lot of use from it.
Remember that some third-party keyboards do not recognize Mac start-up key combos, and that some current Aluminum Apple boards may not work correctly with older Macs. The Al board with numeric keypad (here) says it will work with Tiger. The wireless ones and the short "non-keypad" version require Leopard or higher.

Power Mac G5 Dual 2.5 - Move Hard Drive to another G5??

Hi,
I'm using a Power Mac G5 Dual 2.5 w/ OS 10.5.8 with my Pro Tools 7.4.2 HD3 rig, 2 internal hard drives and tons of external FW hard drives. It's being hinky with me (every time I reboot/restart the Mac, I have to take the side cover off or it won't boot; wierdest problem ever), and being that I don't want to plunk down thousands of dollars on a new Mac and all new Pro Tools equipment, I'm hunting E-Bay for an exact duplicate of my Mac, of which there are plenty. Since PowerPC architecture is long dead, they are dirt cheap. No reason not to have a spare.
My questions are:
If I buy another Power Mac G5 Dual 2.5 machine, and swap the hard drive it comes with, and use my already functional hard drive (with the OS, Pro Tools and all related plug-ins installed), and move over my Pro Tools cards and 8 GB of RAM to the new(er) machine, will it boot up and work without me having to reformat/reinstall everything?
I also see numerous Power Mac G5 Dual 2.7 machines out there as well. What are the chances of doing the same as question 1 with this? I know the processor is different, but would my already formatted and functional hard drive care? I don't think this will work, but I have to ask.
If Question 2 is even possible, would upgrading to a Dual 2.7 even be worth it as far as noticeable speed improvement? Superior Drummer, EZ Drummer and EZ Keys are all real time plug-ins that need the Mac's processor/memory to work. They don't use the Pro Tools cards to work. So, would getting that extra 200 Mhz of processor power even matter?
The reason I ask is that reinstalling the OS and Pro Tools is not the issue; 4 hours and it's done. BUT, reinstalling Superior Drummer, EZ Drummer,and EZ Keys, along with the mountain of expansion packs, will literally take several days of work. If I could just plop my old hard drives and 8GB of RAM into a newly purchased G5 Dual 2.5 or 2.7, and not go through that, it would be AWESOME.
Thanks for any feedback on this.

Just got done making the transfer to the "new" Dual 2.7 G5 I bought off E-Bay. (yes, on Christmas Eve, because....well.... I have no life). Worked dead, solid perfect!!! I'm grinning from ear to ear right now.
I had to reset some pref's in Pro Tools (not an issue), Just got done running Pro Tools through its paces, and it works perfectly. All plug ins run (had to re-authorize Superior Drummer and some related plugins because it detected the change in system serial #, again not an issue). Other than that, it worked like it always has. I loaded every third party plug-in I could find, and every third party program I could find, and so far everything works without any issues. Only exception is Team Viewer locks up when I try to close it (have to Force Quit), but I couldn't care less right now. I use that twice a year if that, and just to have someone help me remotely.
Thanks for the info and help. This made my Holidays.

The Disk Utility, Carbon Copy Cloner, SuperDuper, or similar software. For best results, place the second drive inside the computer or in a FireWire enclosure and boot the computer from it before removing the internal drive.

Startup problems w/ Power Mac G4 (QuickSilver 2002) M8667LL (dual 1 GHz)?

Startup problems w/ Power Mac G4 (QuickSilver 2002) M8667LL (dual 1 GHz)
Starts up with bong and then a long wait then screen comes on with old time smiley Mac and spinning beach ball then another long wait and then OS X loading bar and then a panic screen. Subsequent start, bong, and then hard drive spins for 6 or 7 minutes, then hard drive stops and then nothing. Could this be symptomatic of a hard drive failure?
Thanks very much.

I am pleased to report that I think the problem has been solved. Apparently the strange behavior can be attributed to overheating. After some on line research and the help of people on this list I opened the case and found that the logic board fan was clogged full of lint and dust. After cleaning it I discovered that the fan is inoperable. The computer is now operating with the case open and a small electric fan directed at the logic board heat sink. The computer has been operating flawlessly now for several hours. Will have to replace the bad cooling fan and clean the computer regularly. Thanks so much to all of the people who have responded to my request for help. Would like to mention that a firm with a canine connection charged me over a hundred dollars to report that their diagnosis is a faulty logic board.
Thank you.

Strange power issues

I am having some strange power issues with my six week old Macbook. The symptoms are as follows (I apologise in advance for the length of this post) :
1) If the battery charge is below 50%, and you connect the magsafe charger prior to power-on, the charge light will illuminate until the grey boot screen comes up. Then the charge light turns of completely & the Macbook boots up using battery power. If I disconnect the magsafe connector, followed by the mains and reconnect in the reverse sequence, the light turns green momentarily and then orange (as it should for charging)
2) If I start the coconutBattery application after booting into OSX, while the charge is still below 50%, the same issue occurs again with the magsafe. It appears to happen at the exact time the application queries the battery. I can get the charger working if I follow the same disconnect/mains/reconnect sequence.
3) The issues above also seems to occur when the battery updater checks the battery. The Macbook does not recognise that the charger is plugged in.
4) If the charge is above 50%, then all works as expected. The coconutBattery application does not affect the charger. The Macbook works as normal.
I have tested with a brand new magsafe & a new battery - symptoms are identical. I have noticed several other non-consistent issues - the flashing green light/orange light on the magsafe connection, unusual battery life calculations (70+ hours).
I have performed calibrations & reset the PMU and the PRAM, and have all current updates. And I have spent a large amount of time in the forums looking at similar issues without much success. I am beginning to suspect the logic board (DC chip) is at fault, however I dont relish the idea of dropping my new Macbook at my local Apple Repair centre & getting it back three weeks later with the same issue.
My current cycles (on this new battery) are at 2 with a full charge capacity of 5142 mAh.
My questions to the community are:
Does anyone have a similar experience with these types of symptoms?
Or can someone illustrate on what would cause the Macbook to believe that the magsafe was disconnected? Whatever internal system call the coconutBattery application uses to recover details from the battery appears to trigger this behavior.
I would appreciate any thoughts on this one.
Macbook Core 2 Duo - 2GB RAM Mac OS X (10.4.9)

Just another observation, based on reading some of Apple's documentation regarding the AC charger:
"If the adapter works after this 60-second "rest," you most likely have a line noise issue with your power source that will require you to reset the adapter (by repeating this moment of rest) periodically. This happens when the AC adapter's over voltage protection feature senses ground noise and then turns off the adapter."
Could a sudden draw of power required at a 50% and below charge trip this over voltage protection feature? I know the charging draw varies based on current battery level.
I have tested this in UPS protected boards with the same result.

Power Mac G4 MDD Intermittent Boot from Internal HD?

I have a Power Mac G4 MDD with a 1.42G Dual Processor, 2GB Ram using a 500GB HD operating OS 10.5.8 The problem I am having is that my computer will boot just fine for a week or so then all of a sudden it won’t boot up at all from the internal HD. Here are the symptoms; I get the ‘chime’, then the grey screen appears with the black apple logo and I see the ‘spinning gear’. The spinning gear stops (after about 15 secs) then it goes to a light blue screen and just sits there forever. I usually see this ‘blue screen’ for about 2 seconds just before my desktop appears on the screen during a normal boot. I could go home tonight and it might boot up just fine, I don’t know, but it’s very frustrating. Things I have tried – ( I have two MDD’s so it’s pretty easy to troubleshoot) but still no successful boot sequence.
1. Reset PRAM
2. Changed MOB battery
3. Attempted a boot from another known good HD
4. Removed the 500 GB HD and installed in another MDD and it boots every time.
5. Replaced Motherboard with a known good spare I have.
6. Swapped out RAM modules
I’m not sure what’s next? Processor?, Power Supply??, Video Card??
Maybe someone out there has seen or witnessed this strange occurrence on their MDD?

I have not reseated ALL the connectors but I will try that first tonight. I removed the AC last night so when I get home I will power it up and try again. When I can get it to boot reliably, it's usually been following an AC outage overnight or a couple of days.
Thanks,

Power Mac G5 DP 1.8, won't to enter in Open Firmware, and no OF comm. exec.

Hi Guys,
It seems to strange but my Power Mac G5 DP 1.8 Ghz, cannot enter in the OF and no commands are accepted by the OF (like boot from cd pressing C, or reset Pram, or everything else)
I'm not sure but probably after the last upgrade ( november 2004 if i remember well) but i'm not sure.
i try all this things:
1) reset SMU by disconnect the power cord for 15 minutes
2) change the Keyboard
3) delete the Password for OF (but didn't sets up)
4) i use the cd with the Apple test, but all is reported as good
The problem is affecting also the sleep mode, when my Mac go to sleep there're no way to wake up !!!, i can only force the power off.
HELP !!!
I'm alone with this problem on G5 DP 1.8 ??
I see many post regarding problem on G5, but i see only on a SP 1.8 !!!
Anyone have idea ?
thx
Fabio

Sorry, i miss some info,
when you press the key on the keyboard nothing happen, and one thing strange are 3 "stock" of noising sound immediately after the white screen with the apple appear on the screen.
After the boot everythings are good, the system is stable, is fast,and the sound is nice.
Nothing could thing to a problem, if i wont to start with another disk or from a cd, the only way is to chose it from the system preferences.
Also the sound volume is "saved" in the pram,so if i shutdown the Mac with no sound, when the mac start the sound is at level 0, so the pram is working good.

Power mac G5 turns on but will not boot up

Hello,
I have the last power mac G5 quad core made before apple switched over to intel. I have not used he computer in about 3 month and it worked fine when I put it into storage but when I tried to turn it on today it will not boot up.
There is constantly a yellow light on near to where the RAM snaps in even when the computer is off. (this is the 3rd light up from the bottom and the only on that is on at this point)
When I press the power button a red light turns on for about one second. Next to this light are the words LED806 Checkstop and it is offset to the right of the other lights a little bit when looking into the side panel of the computer. This light also lights up briefly when I press the power button to turn off the computer.
After pressing the power button another red light turns on just above the yellow light that is always on and the screen is still black. Then the screen eventually turns grey with the apple logo as it normally looks except some of the pixels are off colored a bit in square patterns across the screen. When this happens a green light turns on just below the yellow light. Now there are three lights on all at once.
Next the screen briefly turns light blue and then a little darker shade of blue and the computer will not boot up or go any further than this point.
Can anybody tell me what is going on here and is there any way to fix this?
Is there any way to reset or reboot the computer this the install disk?

"Dead" G5 Power Mac

Looks like my faithful G5 Power Mac (2004, Dual 1.8GGHz) has called it a day! It does not start up and after a few minutes the fans rev up. I have tried all the recommendations made in this forum, to no avail.
Please could any community members tell me if I can remove the hard drive from the Power Mac (Western Digital WD740GD) & place it in an empty drive bay of an Mac Pro (Early 2009) to access data on the hard drive, or will the presence of an Operating System on the removed hard drive cause a problem with my Mac Pro booting up?
Thank you for your advise.

Good news on that.
Do you have another thread on the G5 problem?

Power Mac G5 Dual 2.5 freezes up, Power Mac G5 Dual 2.5 freezes up

Hello
I inherited a Dual 2.5 PPC Power Mac G5 from my sister. She was having problems with it suddenly freezing up. She replaced the hard drive but that didn't fix it, and sicne she had a newer Macbook Pro she gave up on it. When I got it I replaced the video card on it with an ATI Radeon, and it seemed to run fine for a while, and then the problem returned. It seemed to have returned after I did all the Apple software upgrades on it (It's running Leopard), but that might be a coincidence. I noticed under Diagnostics on the power up test that some RAM had failed. I also noticed that it was running on 1 gb of RAM even though 2 gb were installed. I removed the faulty Ram (4 256 mb dimms) and hoped that that was the problem. Unfortunately it wasn't. I also installed a temperture reading program. It showed that CPU A is running around 80 C at times and is usually about 10C hotter than CPU B. I'm not sure though if 80C is normal for a G5 or not. I noticed that when it was unplugged that it wouldn't retain the time and date, and took a look at the battery, and sure enough it was starting to leak (but hadn't leaked on to any components). I've ordered a new bttery for it.
I ran a check with Disk Utility and found the HD was ok, but permissions were a bit messed up. Disk Utility wasn't able to fix some of the permissions, but i don't think this is the underlying problem.
I've also opened it and gave everything a thourough vacuuming and cleaning and reseated any removable parts. I took the cover off the liquid cooling unit and vacuumed out the dust. There didn;t seem to be any coolant leaks I could see.
Any suggestions on where I should go from here? I unfortuantely don't have any of the disks for it, so I can't run the AHT until I find one for it (the one for my Macbook Pro wouldn't work).
Sometimes it just freezes. Other times it freezes and the computer fans go on high. It will finally get to a point where it shows the grey multi-language restart screen (where it says to hold down the button to shut it off and the restart).
It was frustrating because on my workbench it was running fine after I switched the video card, and it didn't freeze at all. When I moved it to our computer desk though, the problems returned. Tonight it was to the point where it didn't last 5 minutes.
My thoughts are:
1. Maybe All the RAM is bad
2. Maybe the dead battery is messing it up?
3. When it is heating up with use, something is expanding and not connecting any longer.
What are your thoughts?

Hi Curtis,
I'm not sure though if 80C is normal for a G5 or not. I noticed that when it was unplugged that it wouldn't retain the time
Nope, not normal, way too hot, above 70°C... If you have any temps in the 70°C/160°F range, that's likely it.
Have you blown the dust out of everything with high pressure air?\
1. Maybe All the RAM is bad

Power Mac G5: A common dilemma: to upgrade or buy new

I know there are a lot of discussions on this topic going around, but everyone's needs and uses are different, so I'd appreciate any input on my situation.
I own a Dual 1.8 GHz Power Mac G5 with only 1GB RAM and a failing 160GB hard drive.
At this point, I basically only use this machine for web browsing, iTunes, and Garageband, and am running Tiger.
I had been having some major hard drive problems so I wiped my system and re-installed Tiger , importing everything from my iBookG4 (which, I recently dropped and the screen connection has failed and is unusable except for as an external hard drive in target disk mode. it is probably too expensive to fix for what its worth so I will probably try to sell it for scrap).
Anyway, everything was ok for about a week until I opened firefox and noticed all my settings and bookmarks were gone. When I restarted my computer, my music, pictures, documents, and movies folders were all unable to be located (although my applications were fine and my hard drive still showed that the space was the same). I'm not sure if I imported some problem from my iBook or if my hard drive was just messing up again, but I've decided that I either need to upgrade or get a new computer.
Basically, I am thinking about upgrading my memory, getting a new hard drive, and upgrading to leopard (mostly for time machine). Or, possibly getting a new iMac or waiting a bit and then getting a new iMac or even (gasp) a PC (highly unlikely).
I was going to get the memory from ramjet and I was thinking of only adding 1GB to make 2GB but could be persuaded of getting more but 400Mhz DDR memory is a bit more expensive than other types. As for the hard drive, I was thinking about getting a Seagate Barracuda 7200.10 SATA 3.0Gb/s 320-GB Hard Drive with a 16 MB cache. I could pay $15 more for a 500GB with 32 MB cache but i really don't need the space and am unsure whether the cache will really help much. Seagates used to have a pretty good rep I thought, but now they seem to be getting mixed reviews, so I don't know.
Obviously, I am no computer expert, so any help would be great. Would it be worth it to spend between $250 and $325 to get the memory, drive, and leapord when I could maybe sell my G5 and my 23" apple cinema display (the old clear kind) and get an iMac? I could maybe get about $700 - $800 for the G5 and around $300 - $350 for the display. Will an iMac be faster than my G5 with the upgrades? I don't think I need a mac pro for my current uses.
Thanks for your help. Feel free to offer advice on what to do with my iBook too.

Memory: $60 for 2 x 1GB, I'd call that very affordable.
http://eshop.macsales.com/item/Other%20World%20Computing/3200DDR2GBP/
Disk drives: 2 x $69 for pair of WD Caviar 640GB
http://eshop.macsales.com/item/Western%20Digital/WD6400AAKS/
It is not about capacity as much as speed and quiet, cool, and how well it handles OS X. I use half the drive, other half is unformatted free space. I'd skip the Seagates. 7200.11 is current.
I expect new iMacs in '09 as they are overdue.
Hard drives you keep or put in FW case.
Current Leopard is 10.5.4 DVD but would be nice to see another DVD now with 10.5.6, $109 (Amazon, maybe less Newegg?).

Sounds like three things you may not be doing or have:
SuperDuper for backups. You don't need Leopard.
Disk Warrior. Everyone, or I should say "HFS+" needs #1 disk repair utility.
Backup drives. Two backup sets you switch between, and a small "emergency" partition on one for running Disk Warrior and such.
I replace or move older drives to backup use and put new boot drive in on a yearly basis. Some new drives and memory should be all you need. A couple people even stress their system with graphics and video, and upgrading to 3 or 4 new drives revived their system so that they could hold on and wait another year.

I want to run hardware test on my Power Mac G5 but it isn't working.

What I tried:
I have the original install disc 1 which came with the machine in the optical drive (which is the usual one). I printed the hardware test guide which is on the disc, disconnected everything but mouse, keyboard and monitor. I tried to boot, pressing the Alt/Option key, but the "system picker" or boot menu won't show up. What happens is what somebody described as for "old world" macs: my system boots with no finder window open and without the white screen and apple logo (which usually shows up during startup).
I also tried something I found in a user manual pdf for Power Mac G5 on the apple archives: Booting and press-holding C (btw it's strange that this manual says something different than the manual on the original disc). What happens here is that my machine is booting from the original disc but it boots in Installation mode. I looked at every drop-down-menu I could find there for several times but there is definitely no hardware test, since this is thought to install Mac OS 10.4.
I also tried the Intel-way and holding D during boot, but no surprise, it only booted the first drive (like it should on a pre-Intel).
But something about this all is very strange. Yesterday night I tried all these steps above and when I was close to fall asleep in front of my monitor it suddenly worked and I made it finally into the hardware test. If I remember correctly, I was holding down the C key, but as I said a was pretty dizzy and can be mistaken. I ran hardware test once enhanced and it stopped during ram, giving me an error code I wrote down. But since I made it into the test and was so tired, I thought "lets continue tomorrow" which was my epic fail for this year, I guess. Today I repeated every step, every way I tried but it just doesn't work; and I read sooo many forums and Q&A's.
By the way here is my error code which appeared after 49 minutes (to proof I didn't dream this):
"2MEM/1/4: DIMM3/J14"
Why do I want to do this?
Around the 1st of September this year my Power Mac G5 didn't boot anymore (the fan speeding issue). After reading a little online I came to the point that its either my Ram memory or its my graphics card or its Pram or NVram. I resetted Pram and NVram, I also replaced battery and then it booted again for one day but on the following day it didn't. I repeated every step but the battery replacement since it was a brand new one. It can only be Ram memory or my Graphics card (which is the standard one for this machine).
Since then my Power Mac was rarely in use, only two or three times in Firewire Target Mode to access some of the data. Yesterday I wanted to do this again; booting it in FT mode but I must have connected my keyboard too late during booting and my machine surprisingly booted just fine! I was so stoked about this! Then I wanted to find out why it didn't work for a while and started several steps. Ran maintanance scripts, repaired the system volume, checked for enough free space, checked my Ram and then I stumbled on the interwebs over the hardware test which is delivered on the original install disc 1 and I never heard about this before (strange enough). What followed is written above.
What do I have?
I have this:

Sorry for the German but I think you still get it. The PPC was delivered with 10.4 and I bought it used from a friend with his original Update disc to 10.5 and I updated to the max, 10.5.8. I have 2x 1TB drive (similar ones) together as a Raid0 and three partitions on it. (I know now that it doesnt make that much of a sense).
Yeah so I really want to find out why my machine didn't work for three months but since it is so old and I'm a student, it doesn't make any sense to me to go to an Apple store or similar to have it expensively serviced since there is no guarantee that these guys really help you (heard some stories about the local stores here).
Is there a way to re-access the hardware test and run it to the end?
As you might have noticed, I'm pretty desperate. I would soooooooo appreciate it!!
Best,
Erik

"2MEM/1/4: DIMM3/J14"
Replace the memory in the DIMM 3 slot.
If you are running Mac OS X 10.5 you can use this program to test your G5's memory:

It will subject your RAM to a more thorough test than Apple Hardware Test.

Hey, I'm fixing up a Power Mac G5 for a friend, he gave me a Cinema HD 30' display to use with it. My problem is, the Power Mac G5 doesn't have a place where I can plug in one of the display's cords. the cord is called a "DC power (24.5 V)"

So the Cinema HD's DVI goes in fine, I don't remember what video card is in the computer, all I know is it's Nvideo, it's old, only like 256MB, but does have two DVI ports. Anyway, then the display's firewire and USB can go in. But there's this weird thing, had to do some research to figure out what the connector/cord is called. it's the size of a USB, rectangular with oval sides. It's called a "DC power (24.5 V)" I'm like, what the heck is this thing? it won't go into the computer anywhere, I'm assuming I need some sort of adapter?? Help please, if I need an adapter or video card, links would be extremely helpful.
Best regards,
Poly

I don't believe so, I have a DVI to ADC adapter I was messing with, my DVI from the display plugs into the adapter, then i grap the adapter's ADC connector, and it does not go into my Power mac G5's video card. So that confirms that the display is DVI, and works with my DVI video card perfectly. It's just the one wire/connector that apple calls the "DC power (24.5 V)" that won't go in anywhere. Basically the display has a DVI connector, firewire connector, and USB, which all go into my Power mac G5 fine. However, it has another wire with a connector that won't go in anywhere, from what I've read off the teach specs of my Cinema HD 30' that final connector/wire is listed as "DC power (24.5 V)"
So my problem is with that. I have NO idea what it does, or goes into. When I google "DC power (24.5 V) Apple" it comes up with weird images none of which have that connector. So I'm just so. Confused.

Use iMac in Target Display Mode with a Power Mac G4

I would like to connect my Power Mac G4 MDD (Model = http://support.apple.com/kb/SP63) to the new iMac (27 inch, Mid 2010) in Target Display Mode. That is, I want the new iMac to be the display for my Power Mac G4. Has anybody done this (including using the iMac 27 inch, Late 2009, which can also do this)? In a general sort of way, this sort of thing is described on this support page: http://support.apple.com/kb/ht3924.
The problem: The iMac requires a Mini Displayport connection. The PowerMac has ADC and DVI-I display connections and also came with an adapter for converting DVI-I to VGA. How can I convert/adapt to get the appropriate Mini Displayport connection?
Gefen makes a converter (http://www.gefen.com/kvm/dproduct.jsp?prod_id=8913) that will convert DVI-D to Mini Displayport, but the description explicitly says that it will work with DVI-D only while my PowerMac has DVI-I. I know that these are two different, incompatible connections.
Is there another converter that works with DVI-I? Or is there a way to adapt from DVI-I to DVI-D? Or how about a VGA or ADC to Mini Displayport converter?
Thanks.

japamac-
Thanks so much for your reply. You're right on target for what I'm looking for and that article is VERY helpful! If you don't mind, I do have a couple more questions/clarifications.
1) First, I think that I didn't read the Wikipedia reference concerning DVI (http://en.wikipedia.org/wiki/DigitalVisualInterface) closely enough. It includes the following paragraph. If I understand it and what you said, it shouldn't be a problem to connect the male DVI-D of the converter into the female DVI-I socket of my Power Mac. Right?
+The long flat pin on a DVI-I connector is wider than the same pin on a DVI-D connector, so it is not possible to connect a male DVI-I to a female DVI-D by removing the 4 analog pins. It is possible, however, to connect a male DVI-D cable to a female DVI-I connector. Many flat panel LCD monitors have only the DVI-D connection so that a DVI-D male to DVI-D male cable will suffice when connecting the monitor to a computer's DVI-I female connector.+
2) I'm not clear on the difference between the Altona AT-DP200 and the Gefen converter. The Gefen converter is somewhat less expensive, so I'm trying to figure out what the downside is. The article you mentioned says that the ATP-DP200 "doesn't scale images", but that seems to only be an issue if I'm trying to connect other devices (PS3, Blu-ray), not if I just want to connect my Power Mac.
The description of the Gefen converter includes the following drawbacks:
+The only major drawback to Gefen's solution is no support for VGA devices or HDCP. A minor gripe would be the fact that the Gefen device only accepts one input resolution and only outputs one resolution (1920 x 1200 at 60 Hz). These limited options aside, the Gefen device looks like it could do the basic trick of transforming a DVI signal to Mini DisplayPort so that you could use your 27" iMac for a few more purposes, provided that the input signal carries the required 1920 x 1200 resolution.+
I'm not clear on what the practical impact of those limitations would be. I don't think the the lack of support for VGA devices or HDCP is an issue for my application. But I'm wondering about the statement that it only accepts one input resolution and outputs only one resolution (1920 x 1200) and the need for the input signal to carry 1920 x 1200. I take it, first of all, that the Power Mac can supply that input resolution. And, what is the impact of the device only having that resolution output to the iMac screen? That is, how would that look on the screen, ugly or okay? Finally, would the Altona device provide a better looking output on the iMac screen because it can apparently handle different resolutions? The manufacturer's description says, "Resolutions: all resolutions up to 1920x1200 (It is Important to select one of the resolutions that display
is capable of displaying, refer to your display’s users manual)."
Thanks again.
