6400/6500 boards work with the 5xxx backplate, right? Those seem to be more common than 5400/5500 boards so I might just get one of those.

For the hell of it I threw my 580 board in the 5260 and it did actually power up! It also gave chimes of death and there was no picture, but at least I know the machine powers on.

the 5400/5500 6400/6500 boards are identical.
I think I have a 5400/6400 board. Maybe a couple of them. I will look.

Yeah, 5400/5500 boards and 6400/6500 boards are the same but 6400 and 6500 machines and their boards seem to come up for sale a LOT more often...

I stuffed a 6500 in my 6400.

Oooh, how fast of a 6500 was it?
The 5500 didn't go past 275MHz while the 6500 went up to 300...

Not sure, did it years ago.

I'd like to get a 6500/300 (and get my 9600/300 up and running) and benchmark the two to see just how much faster the 604 is than the 603.

Turned out the reason why it wouldn't boot initially with the 580 board is that my one RAM stick is bad. That blows that I have a bad stick, but it's nice to know that the machine will work with a new board! Looks like this 5260 either hasn't been updated since shortly after it was made...

Do you have the Apple remote to turn it on/off?

Nope, all I got was the unit itself and a power cord.
Wiped the HD and installed 8.1 but now it gives a Sad Mac trying to boot off the HD. Will have to look into that.

Oh no...my luck finally ran out, my first bomb victim. Thank goodness the ROM SIMM (I'm assuming that's what the solitary stick is) and CPU were unaffected so I can transplant those to a new board.

Anyone got tips on dealing with that huge patch of rust? I was going to try vinegar and baking soda...

The VRM is toast, and maybe the audio card. The seller must have known about it since he removed the RAM (or did you do that)?
As far as the leak goes if it came in contact with water you have HF (hydrofluoric acid) which is something you don't want to touch with your bare hands (very nasty). Baking soda and water to get rid of any acid, a can of coke and a scouring metal pad to clean the rust. You might want to paint it as well.

I didn't touch anything inside the machine, I just opened it up and took pictures. As far as I can tell the seller never opened this machine up (because otherwise he'd have noticed the battery explosion!) so the RAM must have been missing since before the computer was sold to me. What is the VRM? Is that the little board next to the battery that got toasted?

Yes, voltage regulator which is needed for the Beige G3 to work.

Ack! And that's not even a Maxell!
I think parts for the beige G3s are still relatively available, so perhaps you can simply find a new one?
In fact, would an AIO logic board fit inside a MT or DT case? If so, I might have just what you need to get that back up and running.
PM me if you're interested.

I know there are boards on eBay, I just have to match the part number. I need to put on some gloves and get that nasty board out of there pronto...

My college was cleaning out a hardware closet and they dug out an original Bondi iMac and they let me have it. It's actually a Revision A model, which is pretty cool. I snagged the VRAM module from a Blueberry trayloader they had that turned out to be dead (wish I snagged the CPU card too, oh well) so I can upgrade it a bit when I'm putting in a new hard disk. I have two sticks of 64MB PC100 from a ThinkPad but I dunno if it would work...

The college recycling pile struck (relative) gold again and I snagged myself an HP DAT24 internal tape drive! Now if only I had something to put it in. And tapes.

I got the beige G3 motherboard in and installed it and my god, the thing works after all! Kinda.
The front LED connector essentially disintegrated and the CD drive is cranky and probably needs its laser cleaned but it's so rewarding to bring such a heavily damaged machine back from the dead.
