I think the CRT probably is probably already discharged at this point, as it is no longer really connected to the analog board. It is good to be cautious around CRTs because they are very delicate, but I think the main risk is probably not there at this point. Of course, it wouldn't hurt to go...

Would you be willing to sell the motherboard?

From what you have described, I think the CRT in this computer is (semi)-officially toast. The sizzle you heard was likely the sound of air rushing into the (no-longer) vacuum-sealed CRT. The pins look extremely bent out of shape, and I doubt that whatever event bent all of the CRT pins would...

Normally, this guy seems to know what he is doing. I think he just doesn't have much experience with surface-mount soldering. He has done many other videos about Macs which provide some pretty good advice and show proper techniques. He has also provided CRT warnings in many of those videos too...

I love this idea! I wonder if these are small enough to fit powerbooks too? Either way, I think cheaper SCSI emulators for old Macs are a good thing. It always hurts me a little to buy a product that costs more than the computer itself did, and I think as long as performance is on part with...

I'm glad I'm not the only one to spot the resemblance between the mouse and Cybertruck. In fact, I made this photo shortly after the Cybertruck was announced. :)

I guess I'll contribute to this tangent, too. :) It looks like PE connectors also sell dual 30 pin sockets. The product they offer looks similar to the eBay product that @JDW was discussing previously. Thankfully, PE Connectors provides technical drawings of the sockets, so one could...

There are some microswitches at the front of the floppy drives which can get dirty/fail and cause some strange issues with ejecting. There are also leaky capacitors that can be replaced on the floppy drives too. It is probably possible to fix at least some of the drives, not to mention that...

@Will Cheyney, Did you ever get a 10Mbit ethernet switch?

I read the chapter on ADB in Apple's book last year while troubleshooting one of my SE/30s that didn't have a working mouse. I don't completely remember what it said about hot swapping, but as far as I can tell, If you are doing the switching with something like a microcontroller, the wires...

This is a pretty good point. The listing for the product I found says that the LED strips can just be cut down to size, which in theory would take care of the bulb length issue. As to whether or not the replacement driver board would fit or be electrically compatible... I guess that would be a...

I've never really seen much about this before, either (certainly never any written instructions). It sounds fascinating -please keep us updated with how the diagnostic mode works out for you. Maybe I'll have to start using it with my Macs too!

Hello, I have an iBook Clamshell with a screen that seems abnormally dim. I read that over time the CCFL backlights inside LCDs gradually dim as they wear out. I did a bit of poking about online and found some kits that seem to be able to replace the existing CCFL modules inside old displays...

There is a book that Apple published called "Guide to the Macintosh Family Hardware". It has quite a bit of documentation for the ADB protocol (among other things), so it might be useful for your project. I think there is probably a copy on the Internet Archive somewhere.

If I understand correctly, I think the sounds the computer is making mean that it is crashing shortly after starting up. My best guess is that there is still a broken trace somewhere on your board. It sounds like there was some considerable capacitor leakage, so it is very possible that...

You should make sure your multimeter can do continuity measurements. This means that it beeps when the two probes are touching.  I think that this board could probably be repaired. As to whether or not the amount of time, money, and effort required to fix the board are worth it, well, that's...

I cannot see anything connected to the pad highlighted in red. It probably was just an extra pin included in the chip package. If this is correct (others please correct me if I'm wrong) you should be fine without it.

These computers come with a special bracket to attach the drives together. I sold my dual floppy SE, so I can't provide a picture, but I am sure someone else here can take a picture.

I think you can do this with an mSATA to 2.5" IDE converter and a cheap mSATA SSD. This should also be cheaper than the product sold by OWC...

I'm waiting for another battery pack to arrive in the mail at the moment, but as soon as I make a working battery, I promise to make a thread detailing the (more difficult than expected) process. ...OK -I'll describe the melted battery here too. :) What happened is that after I spot-welded the...
