Power Macintosh G3 no boot

[Ih8reno]

Hi all,

I picked up a second beige tower G3 today and decided to put all the best parts into the best case. My original G3 is a 333mhz ith a very rusty case due to water damage from the previous owner. The new to me machine I just picked up has a 266mhz and a personality card so I decided to swap over the best of the 333 including the cpu into the 266. After the swap the frankenstein mac will no longer boot, and neither will the rusty one. I swapped back the cpus and no difference. I took out all the cards and unplugged both drives and still nothing. PMU reset also was done and no dice. Anyone have any other suggestions?

Thanks in advance

Just wanted to see if anyone had suggestions. I was able to get a chime with the one I was trying to upgrade by reinstalling the original cpu and found a stick of ram which seemed to work. Still no video. Any help is appreciated

Did you change the CPU speed jumper on the logic board? I just pulled out my G3 tower after many years of storage and it definitely has some quirks. It sometimes requires a warm reboot to get to the desktop. What OS?

Well I put both zif modules back in their respective machines so the jumpers weren’t moved (I figured that they may be one issue). I believe my original g3 which was rusty had 9.2 on it.

Have you tried a warm reboot?

What happens when you push the power button?

It chimes and the hdd seeks. Then all you hear is the fans and the hum of the drive

Push it again until it chimes.

I took off the jumper block I had removed from the original rusty one and put on the bord. Replaced the jumpers from the ones which were on the new one. Success! She boots and displays. In assuming they had all sorts of rust and crud on them that interferes with the boot.

Next everything shows up but the Zip drive doesn’t seem to see my disks.

Very happy here! Thank you so much for all the suggestions.
