Hi guys,
I'm new on this forum! I recently bought a Power Mac G4 2000 QuickSilver. It works and most importantly It boots up. When It boots up, Mac OS 9.1 starts and after the Welcome Screen It says "Illegal Instruction - Restart the Mac by pressing the shift key for disabling temporary all the extensions"(The Mac OS 9 version is in Italian). I also booted in Safe Mode and nothing, same error. Unfortunately, I don't have any Software disk from the Mac (I have only the Software Install and Restore from an iMac G3). I also tried to burn some CDs but in phase of booting hit ejects all of them. So please help me to restore this Power Mac.

From the picture your drive is terminated but no id is assigned yet. Use a jumper to assign id 1 and do that on the adapter as well. It is possible the adapter needs to be assigned the id instead of the drive. That might be the issue why its not showing up. I guess there is no auto assignments.  Besides the hardware is older and i dont know much about the internal bus and chip but you might have to use the delay on the drive to wait for the system to get going before it is seen. The cable you got does it have a piece of plastic on the end like a angle? If so thats a terminator. Atto cards can be set to auto terminate from memory. Dont know if all do that but recent versions do.

You're right again GaryN - Good Job!!

I think they have different bus speeds - IIRC the dual 1ghz has 133Mhz bus - the other one single 1.25Ghz has a 167mhz bus - I think thats the only major difference. Hold on to one of the power supplies.  :D :D
Actually, Jaki's wrong on this one. Both machines will have 167MHz bus speeds. Only the single 1.0GHz and the 867MHz CPUs had 133 Mhz bus speeds.

Don't think of them as separate machines. Think of the two as a collection of parts and sub-assemblies that are completely interchangeable.
Take the best parts from both and put them together. Save everything else - especially the extra power supply - for spares.
If you're going to run only OS9, use the single 1.25 processor unless you'll be regularly using one or more of the apps listed in this post:

The SCSI ID, whether the drive is terminated or not, and whether term power is on or off is set by jumpers on the hard drive.

You must be sure both drives are not configured for the same SCSI ID, and also not for the SCSI ID of the computer itself.

If the adaptor you have is to connect a 68 pin device to a 50 pin bus, you will lose the added performance of the hard drive with this arrangement. For this arrangement to work, you must turn OFF termination on the first drive in the chain, and ON for the last drive in the chain. unless the internal SCSI cable has a built in terminator at the end, in which case termination on all connected drives should be OFF.

The problem may be that the adaptor is actually to connect a 50 pin device to a 68 pin bus, and I don't think this will work at all. 68 pin devices are usually backward compatible with a 50 pin bus, but only with the correct adaptor, and then the increase in speed of the device is lost.

Better to get a PCI SCSI host adaptor. They are not expensive on E-bay. Make sure the one you buy has an internal connector. I think some had external connectors only. ATTO made nice ones.

Wow thank your for the very important and detailed info, I am aware it lowers the speed and it is being done for just reliability as the OG drive will likely fail soon like the slave did as they should be around the same age. I did look on here but all at least pci-ide or sata adapters listed I cant find anywhere or they require the eprom to be flashed which if it was me I would do but I don't want to give the client anything that could be non reliable in the future. I will check the main drive in a couple days to see what jumpers are on it and how it is terminated. Is there a simple way to tell if the 50 pin cable is pre terminated vs using the jumpers on the drive? This is the adapter I have gotten https://www.amazon.com/gp/product/B074TYC7KC/ref=ppx_yo_dt_b_asin_title_o03__o00_s00?ie=UTF8&psc=1 Once it is working I plan on copying the contents of the OG drive to the new one and then making it the first drive in the chain and removing the OG to be stored as a back up.

I am trying to use Bernie ][ the rescue to make some IIgs disk.  I am using Mac OS 9.2 on a Beige Powermac G3 desktop.  Whenever I try to mount any disk images inside of Bernie and restart the emulator it will give me an error showing all kinds of different letters and numbers.  I have tried dozens of images with the same results.  Anyone use this and familiar with the issue?

Hi, I have a Client that has an 8600 with 9.1 on the original ID:0 SCSI 50 pin drive which I believe is the term power device for the BUS 0 Chain. It runs fine but I'm trying to upgrade it to a Sun 390-0175 72GB 3 1/2" 10000 RPM Ultra-320 SCSI Hard Drive MAT3073NC https://www.amazon.com/gp/product/B01N4VALK0/ref=ppx_yo_dt_b_asin_title_o04__o00_s00?ie=UTF8&psc=1 with an adapter to have it be more up to date and stay reliable. I was originally called out to help though as they said it had a loud screech noise and the second HDD in there on ID:04 kicked the bucket and was grinding. At this point I am trying to use the adapted drive to clone the existing boot device to it (will 9.1 see it unformatted, and I read you can just drag everything over including the system folder as long as it's mac extended formatted and it will be bootable?). My issue is the second HDD will not get detected in 9.1 in the apple profiler as I don't see any ID: I set it too. The drive that came out has the attached jumpers (looks like it may have been doing Power Term?) but I don't really see any way to replicate that on this adapter. I'm sure I am just not seeing the correct way to do this and would love some advice from this very cool community that obviously seems to know a lot about these specific systems and the technology behind them.

Thanks.
Malcolm

The pics show the adapter, drive taken out, and and the current good drive on the profiler (labeled new hard disk by the client but it is the OG main one).

Today I bought two G4 MDD machines for only $50 for both but I do not know which to make regular use of and which to set aside as a parts or a "just in case this part fails" machine. Both are running great:

1. 2002 Dual 1 Ghz  2 GB RAM  2 Pioneer DVDR  Radeon 9000 Pro 128MB  Rage 128 16MB

2. 2003 1.25Ghz Single, 2GB RAM, HL-ST-ST CDRW/DVD GeForce 4 64 MB  Radeon 9600 Pro 256MB

Drive storage is immaterial, but each comes with 4 80GB IDE drives, and I have more storage and adapters than you can mention in a single post.

OS will of course be OS 9.2.2 since they can run it natively and well, you know the reasons already being an OS9Lives member.  But I do not really know which to make the regular machine. Ideas? Opinions?
