ah yes, the Quantum BlueSCSI.

Looks like the 3rd gen is stuck in debug mode. Could be bad hard drive or a corrupted drive.

There's been a bug in the BlueSCSI V2 and the ZuluSCSI of which the V2 is based that's been happening to a lot of PowerBook users where the OS will freeze when trying to "spin up" the drive. Basically, on PowerBooks, Mac OS will automatically spin the hard drive down after a few minutes to save...

The heat didn’t bother me much. If they had held it earlier, I wouldn’t have been able to attend due to school obligations regardless, so I’m very glad they hold one of these meets during the summer.

And that would be me in the background on the second photo :) I'm clearly carrying some laptop, can't tell which one. I drove off with probably close to 15 laptops.

No schematic in the video, but it's a great watch. Probably the best TDNC video I've seen so far :)

I won’t mind heat too much. Will be too distracted by the old computers :)

It better not storm... This is the once-in-a-year event for me!

Yes.

I’d also like to know, I can add it to my complete Macintosh schematic archive: https://macdat.net/repair/apple_schematics.html

Indeed, that's why it sounds like a speaker - because a voice coil can be used as a primitive one.

It's a sound made by the hard drive's voice coil. Not sure if it's the heads trying to free themselves, or if it's a warning tone that something's wrong. It seems to be specific to IBM Travelstar drives whatever the case may be.

You mean the ambulance noises? Yeah the old travelstars do that if they get stuck with stiction and the likes.

She’s seen better days…

They can and will, it just seems to take a severe leak for damage to be caused. They're certainly better than the 1/2AAs, but they can't be trusted and still should be removed. I've heard multiple cases of people losing LC 575 boards to those batteries.

Very, very low with that method. If you're confident you won't damage anything, go ahead, but I'd try everything else first because taking components off is risky. Do you have a hot air station? I've seen a lot of corrosion cases. The only times you need to worry about corrosion hidden under...

If the battery corrosion had made it to the RAM board then the rest of the machine's PCBs would be completely destroyed, that would take a catastrophic leak. I don't see any corrosion in the photos regardless. Battery corrosion doesn't just "jump around" - if the PCB by the battery contacts is...

How have you confirmed the floppy drive working? Is the problem that you don't have a way to write boot disks? Memory module looks correct for this model. If it isn't working, it's very likely not a soldering problem. You can try, but I'd recommend just touching up all the solder joints rather...

Sounds like you have a bad floppy drive and a bad memory module. I highly doubt resoldering everything would fix that - more likely a bad chip. What type of module is it?

get 'er out! I've pulled two vartas in the past week - one out of a Samsung SENS 800, and another out of a ThinkPad 770ED. Both leaking (of course), neither damaged much. 770ED's connector sustained some damage, SENS 800's didn't. Both survived.
