Hi..

Im new to macs but im a certified PC engineer...anyways, let me explain my story!

Got a 350mhz iMac G3 works well, no firewire ports but has 600megs of ram running OSX (upgraded) and also has OS9 in there also...

I bought from ebay a 600mhz logic board with firewire ports, installed that but i had a yellow power button and a singular beep (dodgy ram) using my new pc133 1 gig...so i changed to the original ram (600megs) that didnt work oddly, then i used the original singular 64meg stick (pc100) it started, but couldnt boot just a flashing question mark... wouldnt boot from CD either using my original OS9 disk (havent got the OSX disks)...then it wouldnt startup, power problems...swapped the power board from my original 350 and it started, but again cannot boot, flashing ? and again power problems...

so i chaged the HDD for a last ditched attempt at a new install of OS9 using my disks... again, wouldnt boot from CD... now i've read and re-read these forums and tried everything you can imagine... cleared NV ram... reset-all..... basically nothing...

replaced my original 350 board, added that seemingly dodgy stick of 512 megs and it started up lovely 1gig ram works a charm... so i'd say...that 600 logic board is duff right?

i mean surely there's nothing i've missed... a simple logic board replacement i thought, get some firewire ports and bingo.... but no!, i wonder now why the 600mhz board was removed....

so what ya think? have i missed something...? as i say my ram upgrade works, booting from my OS9 disk works on my old 350mhz machine... so what to do

please advise.... *get a refund from ebay*
cheers

Yeah, I'd say you're right. It really sounds like you've covered everything and the 600 logic board is no good. I'd go ahead and return it for a refund.

Well you should use two resources in your adventures in upgrading a G3. The are Accelerate Your Mac (and pay close attention to menu items, especially the "database' tab) and OWC (I think they ship internationally ... if they don't, you can get a good idea on what to get).
