It sounds to me like the best thing to do is make a bootable USB drive then. There are several guides and files available online detailing what to do. This link might help: https://apple.stackexchange.com/questions/115120/boot-from-usb-ibook-g4-power-pc

Thanks, everyone! I just placed my (ridiculously large) Digi-Key order. Hopefully, I will be able to bring a few Macintosh Classics back to life in the coming weeks. I'll try to keep this thread updated, as I am sure there will be some troubleshooting in my future.

Hello all, I have a Macintosh Classic Analog board that I am planning to recap, and I am now also the newest owner of four nonfunctional Classic logic boards. I'm trying to put together a shopping cart to order all of the appropriate components, but I am having trouble deciding which parts to...

I'll buzz out that circuit and try swapping the chip out.

I suppose there is nothing at all wrong with buying a copy of Tiger off eBay. You just have to make sure to get a universal version for all the powerpc computers, and not a single machine/Intel version. I suggested it because I can't stand waiting for things to come in the mail. :)

Update on this board: I decided to re-recap everything, as I wanted to make certain that there were not any shorts between the capacitors and traces nearby. I removed all of my capacitors, applied solder-mask to the many exposed traces I found, and put the capacitors back. I also removed a few...

You can also burn a DVD or USB of Tiger yourself, if you'd like. Since you already own several copies (albeit currently non-functional ones) of Tiger, I see no reason why the copies of Tiger floating around the internet should not work. In fact, it is probably less risky to do it this way, as a...

I may be wrong here, but I think that there is more to HD floppy support than just ROMs. I think there is a SWIM chip that also is required in addition to ROMS for this to work. I believe that this is how Mac SE floppy upgrades work, at least.

Unfortunately, I think the only thing to do is to drill out all of the rivets. That was the only way I was able to open my magnetek PSU.

It only makes me wonder how many of my dead boards and chips are actually victims of poor ESD precautions instead of age. Whoops...

Thanks for sharing the video! I enjoyed watching it. Maybe it's time for me to get an ESD Mat instead of only using a wrist band. I suppose my dollar store toothbrushes are not very ESD friendly either.

The computer is nonfunctional, and in an unknown condition. It looks like it has had some work done to its motherboard, but the person performing the repair was unsuccessful. This means that there are lots of potential problems that you have no way of knowing about. Additionally, similar...

Great! Is it okay that the error screen changed slightly between having RAM installed and not having RAM installed? It obviously remained nonfunctional either way. If I understand what you are saying here, the F258s are probably not an issue. Do we have a way to know if the Data bus or Address...

Here is a photo of what happens without the RAM installed:

Do you think it would make sense to replace all of the F258 chips? I have already swapped the UA8 through UG8 chips. I also have another dead SE/30 to swap parts with. I'm not sure what I should try replacing, or which ICs are relevant here, though.

I just checked all of these address lines again, and I found no breaks. Here you go! Sorry about the previous photo's quality. I couldn't make out a mouse cursor or a blinking floppy on the screen.

These are the capacitors I was referring to. Here is a list of all of the parts I replaced in my SoundSticks II's:

What an interesting idea! I can't believe I've never thought of this before!

I also have a pair of formerly broken SoundSticks II. My speakers were full of leaky capacitors, which were causing all kinds of speaker balance/volume related issues. Many of the capacitors were bulging and oozing red goop. I recapped then about two months ago, and they have been working...

Unfortunately, I only have a multimeter to check these lines at the moment. I'll have to double-check the CPU-GLU address lines tomorrow to confirm that everything is working correctly, but no problems were detected on my first pass today.
