Having issue with a Beige G3 desktop...

[Brett B.]

So with that Rev. A ROM... how is your IDE set up?  Rev A is limited to one device per channel... I see you mentioned a hard drive, Zip, and CD-ROM... if you haven't already tried this, remove the Zip drive from the equation and have your HD and CD-ROM on separate channels.  I don't remember what the jumper settings need to be, single or master may be the safest.

Beige G3s often had SCSI PCI cards and hard drives installed when they had both a CD-ROM and Zip, at least from what I've seen.  Both of my towers had Rev A ROMs, IDE CD drives, and 4GB SCSI hard drives, although they were the "server" variant.

As far as the sound goes - try removing the sound/AV card, clean the edge connector off with a soft cloth and reseat it.  One of my G3s is very finicky about things being seated just right... bump it wrong and everything needs to be pulled, cleaned and put back together.

All the beige G3 I saw so far were pretty much configured all the same way. The logic board have 2 IDE connectors, and one 50 pin SCSI connector. In the desktop, the first IDE connector is for the HDD that is installed close to the logic board as you can see in the picture above, the second is for the IDE CD-ROM drive, and the SCSI port is used for the Zip drive. The ZIP is not IDE in these models, but SCSI. So I do not believe the ZIP could interfere with the remaining of the IDE chain. There is a loose 50 pin SCSI connector available above the ZIP to connect a hard drive there I guess. When I connected two HDD to the machine, I unplugged the CD-ROM and use it's connector for the second HDD.

The tower I have does have a SCSI 4 Gb HDD in it configured on a SCSI card. But I think that was installed by the previous owner, not factory from Apple. Apple was using 50 pin SCSI, while this HDD is 68 pin. 

As for the desktop, it does not have any PCI card installed, only the personality card (sound card). 

As far as the sound goes - try removing the sound/AV card, clean the edge connector off with a soft cloth and reseat it.  One of my G3s is very finicky about things being seated just right... bump it wrong and everything needs to be pulled, cleaned and put back together.

I'll try that and keep you informed. 

Thank you for your help.
