| Help for Power Mac G3 tower |
Posted by: toples50 on 2018-07-22 05:26:20
I have purchased the latest and greatest G3 beige tower.(the 333MHz model).The seller sent the machine as untested without hard disk and ram modules.The machine powers up(I can hear the power supply) but does not chime the green light is off and I have no pics.Have to put ram modules to start normally.What do you guys suggest to do?

Put some RAM in it. It won't startup without RAM modules. PC66 or PC100 IIRC. Also check the battery to make sure it is not a bomb. I found a G3 tower a while back that had destroyed the battery holder from battery leakage.

Thanks!
Now I have to connect a hard disk.The machine does not have the ultra wide scsi card.How can I connect a hard disk?

It has IDE as well as narrow SCSI connectors on the logicboard.
IDE drive should be smaller than 128GB to avoid problems.

I can use any IDE hard disk without problem?

To save yourself boot issues, as Bolle noted make the test IDE hard disk < 128GB ... ensure it is jumpered to "master"

ensure it is jumpered to "master"
If it is the only drive on the cable and it is a Western Digital drive, it needs to be jumpered to "Single". IIRC

And *ideally*, you want to have a partition that is =< 8 GB located at the beginning of the drive, or else you may have problems booting (for OS 8.x/9.x, this is somewhat less important, but it's a must if you want to run early OS X on it).

Thanks for replies guys.
I have another one "issue".The startup sound (chime) sounds very very low.Can I fix it?

zap the PRAM 3 times in a row and see if that helps.

I have done this but still nothing...

Some good photos of the motherboard would help. There are some people here who may be able to tell if something on the motherboard needs replacing.
Does your G3 MT boot normally (aside from the weak startup chime)?
If so, how strong are the sounds from the Sounds control panel? Are they weak too? If so, maybe something is up with the speaker, if not, maybe the PRAM battery needs replacing.
Does the system remember the last date & time that was set on it or is it always 1956 at startup?

I can hear clear and strong sound from 9.2 Mac OS.Yes the Mac starts without battery from year 1956.I have to try again with a good pram battery.
