Diagnosing the 9600 From Hell(tm)

Recommended Posts

So I've had this Power Mac 9600 for at least two years now that has just never worked. It just will not boot off a disk. My 8.1 and 8.6 CDs don't do anything at all (and this is after I cleaned the current optical drive and upped the voltage a little) and while it attempts to boot off my 7.6.1 CD, it just bombs like this:

I could still try OS 9.0 or 9.1 I suppose, but is there anything else I can try to finally get this thing working?

 

EDIT: Just tried a burned CD of the 8600/9600 7.6.1 restore image and it just froze on the Happy Mac.

strip the 9600 to basic, 2 memory sticks in 2 banks slot. Original CPU card, All other PCI cards except video card and go from there.

If that fails, swap over to another group of memory sticks and re-test.

Remove SCSI cable from the logicboard, and try boot from floppy.

Check if there is no bent pins in the CPU card slot (you'll need a good torch to inspect properly)

 

If it fails I would be pointing to the logicboard.

Last resort (which I have not seen) is cap leak on the logicboard.

Cheers

With one stick of RAM per bank and every card removed except video, it still bombs loading 7.6.1, even with extensions disabled.

 

EDIT: Somehow by magic it just...worked!

The only problem is that I need to reattach my PCI ATA card as otherwise I don't have a hard drive...

Did you try cleaning the contacts on the board? I would get a can of electric contact cleaner from an auto parts store and clean every slot on the board. I've had weird issues like yours go away from that treatment.

I haven't used my contact cleaner actually, that's a good idea. Right now my problem is that the system isn't recognizing my ATA hard drive, I've tried both 7.6.1 and 8.1 (the OS I want to install) so far and neither one can see it. I wonder if maybe my ATA card needs some bit of software run to make it visible, unless the card is just straight up bad...

 

EDIT: Found the manual for the card, turns out I need at least 8.5 to use it. Guess I won't be using 8.1 after all.

I don't have any SCSI hard drives so I bought an ATA card from someone here so I could use normal PC hard drives.

I think I might have found a problem, if not THE problem...see that line there? That's a relatively deep scratch that goes through the contacts.

I don't know what those contacts are for but having a big scratch through them can't be good.

I might still have a 300Mhz 604e card from a 8600 laying around here if needed. I also still have that boxed G4-450Mhz upgrade for sale (see OLD post in trading forum). Mac ATA cards definitely don't need drivers to boot, the driver is the onboard ROM.

My multimeter is so cheap it doesn't even have a continuity mode, but when I probed for resistance on both sides of the scratch I got 0.00, so I guess it's only cosmetic. Which means I have to try something else to figure out why the machine won't boot to anything other than a gray screen most of the time...

Well I'll be god-damned...I swapped the SCSI CD-ROM for an ATA one from my old beige G3 that got junked running off the other ATA bus on my controller card, re-jumpered the hard drive as Master, and now it's being recognized!

Two years of frustration and neglect finally comes to an end with a 9600 that actually can be used! This calls for a celebration!

I'm so glad too, I was ready to give up and part it out but now I have a powerful machine I can use for uh...uhhh...something.

 

I have half my PCI slots filled and I dunno what to add when I already have a Rage 128 and a 10/100 Ethernet card.

Radeon 7000 Mac Edition and run a 1920x1200 monitor, like one of the big Apple Cinema Displays with an ADC-DVI adaptor (like this one here: https://www.ricardo.ch/de/a/apple-cinema-display-22“-1054491414/)

PCI SATA card to power a SATA card?

Sonnet Tempo Trio and power some CF cards?

Maybe an M-Audio Revolution 5,1 card and hook up a surround sound system to your 9600?

I'm kind of thinking some kind of A/V card, actually. I've been wanting to experiment with video capture and editing on old hardware.

FireWire card?

So the problem was a bad SCSI CDROM drive?   It wasn't entirely clear to me from reading the thread, but I think that was the conclusion to draw.

 

Also, regarding those pins on the CPU card, the bottom row is all power and ground, and there's lots of redundancy, so even if that scratch was all the way through, it probably would not have affected functionality.

Yeah, I guess the problem all along was the CD-ROM drive. Which is a shame because that CD-ROM drive was a replacement for another SCSI CD-ROM drive that was also bad.

 

This Sony ATA drive is loud as hell but it works every single time and that's all I need.

Yeah, SCSI CDROM drives are *old*.   I'm not sure, but I think I've heard that the lasers may weaken with age even if not used much -- although I'm not sure that makes much sense...

 

There are $8 slot load PATA DVDRW drives on Amazon.  TS-T632, IIRC.  But you would need an adapter (slim optical drives use a funny connector).  Might be quieter.

8.5 supports USB mass storage, right?

Barely. USB Mass Storage update 1.3.5, if I remember correctly, requires 8.6, and has an entire eight supported devices listed. Entirely half of them are USB floppy diskette drives. (the support for hard disks should be generic but I also haven't personally tried.)

 

There is a newer USB support file for 8.6, but I haven't had a chance to look at the information for that file.

 

USB support matured for Mac OS 9 a lot and if you intend to rely on it I would run 9 on the machine.
