I'm pretty sure I started my G3 up a handful of times without a battery. According to the manual, the G3 uses a +5V trickle line from the PSU to start so the battery shouldn't be necessary. With that said, it would be worth using a multimeter to confirm that your power supply is putting out the...

Yeah, the ribbons I'm using are one drive per cable, so the master-slave jumpers shouldn't have an effect (although they're both set to master). I'm using images off of the Garden, including the 9.2.2 version. I don't have a SCSI drive to test with, unfortunately; if this is an issue with the...

Unfortunately, a CUDA reset didn't do the trick. I swapped in a personality card from a G3 AIO but the outcome was the same, although the board didn't seem to mind the absence of its precious USB PCI card. A superficial inspection of the board didn't show any obvious capacitor issues, but I...

Hi all! I've been having some strange issues with a 266 MHZ beige desktop G3 I recently bought. It had a bad power supply so it is using a modern ATX power supply with the motherboard jumper switched over. It also didn't have a hard drive with it when I got it so I gave it a 40GB hard drive...

Hah! Unfortunately, my workbench is in my crummy old basement and I'm sure I'd get plenty of false positives using that method, and maybe a case of tetanus. I have replacement resistors coming from Digikey this week. Unfortunately, I didn't order a replacement for that big capacitor. I think the...

Thank you for checking all of that! Strange to have that resistor jumped, but I guess if it works, it works! In the course of working on the board last night with some friends, they noticed that the Bomarc schematic is for 820-0650-B, but my board is 820-0650-A. I don't have the sticker label...

Sorry, I think I did a crummy job of explaining what the problem was. If you could test whether the positive pad of C5 has direct continuity with one of the pads of R7, that would be great! However, I think I uncovered a more serious issue. Both of the pads of R26 on my board have continuity...

Hi everyone! I recently acquired an LC III which I’ve recapped (both the logic board and the power supply). After recapping, the machine will power on, but will not output any video, and only outputs sound via the speaker jack in the back. I get a boot chime which is immediately followed by a...

Thank you so much for this. I recently obtained an LCIII. I recapped the power supply but I'm getting low voltage on the -5V rail. Hopefully this helps me track down the problem!
