    Fixing the floppy drive of a Macintosh SE without dying

    You'll be fine, you sound cautious and that's enough to keep you above ground :). Pretty sure the discharge procedure of the CRT is covered in the first video, if not the Analog Board recap video is a good one to watch too. 800K floppy recap: Eject gear replacement: Analog board recao:

    Macintosh SE/30 M5119 - Year long troubleshooting battle

    SE/30 #2 was really yellow, the bezel was worse than the bucket shown behind it. 8 hours of the 10W UV LED light in a box lined with foil and slathered in 12% Peroxide Creme worked really well once again; like new. I did remove the Apple logo for the process, had one bleach out on an SE...

    What's the best way to fix a stripped-case screw hole?

    But the CRT would still be loose in that corner, needed to keep that altogether.

    What's the best way to fix a stripped-case screw hole?

    I would do that with metal but plastic is easier to fix. I won't say the following is the best way to fix a stripped case thread but I can say this definitely worked for me. Take a small-medium size clip tie and cut two pieces of it as long as the screw threads are: If the case isn't badly...

    What's the best way to fix a stripped-case screw hole?

    Specifically I'm looking to fix the screw hole where the CRT is grounded to. My front case/bezel arrived with the CRT ground hole in a stripped condition and when that screw pops out, the ground wire lets loose and I get video distortion. I've heard baking soda and super glue works to repair...

    It's not that UE8 bodge wire causing the weird screen distortion in the video above, I just tried SE/30 #2's LB and it's doing the exact same thing. Glad in a way no to have to rework the #1 LB. Will try an SE AB and CRT tomorrow. Thinking about getting this trimmer set for adjusting the...

    I do have the green UV mask stuff, will put that on the spots I scraped, thanks! Here's my UE8 bodge wire from Pin 10, this goes to the via under UC8: Going to need to remove UE8 and get rid of that bodge, or use what's left of the existing trace instead, reason being it causes video...

    The ultrasonic cleaning with the correct Elma TEC Clean A1, should've neutralized and removed any further corrosion. I already have a new V5 Reloaded board that I was going to use on this project, but will sell it to someone else who can use it. Thanks.

    Macintosh SE/30 M5119 - Year long troubleshooting battle

    Thanks so much guys! An interesting thing to note about the fix, is that I checked the Data and Address Matrix's, multiple times, it seems to me that perhaps D(1) was just hanging on by a sliver, or a thread of conductivity and when I did the Ultrasonic cleaning, it blew out the remainder of...

    Macintosh SE/30 M5119 - Year long troubleshooting battle

    SE/30 #1 logic board now works also!! Turns out my simasima problem was missing D(1) all along. I had replaced my CPU socket to aid in troubleshooting, went back over all of the pins today and noticed D(1) was missing from CPU to socket pin, touched up the pin, got continuity to FPU UI5 Pin 2...

    It took the Vevor 10L Ultrasonic nearly 3 hours to heat the water to 65°C, had to bring the unit indoors because it was 65°F outside and seemed to contribute to the slow heating. Will return the 10L 180W model, and try their 15L 240W model instead, it's $2 more and should fit a logic board well...

    Macintosh SE/30 M5119 - Year long troubleshooting battle

    On page 24 (PDF pg.27) of the Simasima Repair Guide it says a 10L Ultrasonic cleaner is the bare minimum to fit the SE/30 logic board. Picked up a Vevor 10L for $110. Pulled UK6 Video ROM chip, UK8 CPU and all the RAM and ROM SIMM. The LB doesn't exactly 'fit', need to tilt it and rest on...

    Thanks to JDW once again for his excellent videos, he just saved me from myself by noting at the end of the video below, that the 1.44Mb has (2) different caps than the 800K SE floppy's. I had ordered the caps for an 800K drive, it had been a while and I forgot that SE/30 #2 came with...

    Got through the recap of SE/30 #2's PSU and Analog Board today, will hot glue the caps when the new Noctua fan arrives: The fan will be here Sunday and this can go back together. The brightness knob has a sun spot on it, will treat it at the same time as the case and mouse/KB, with 12%...

    Macintosh SE/30 M5119 - Year long troubleshooting battle

    Turns out my image I made of System 7.5.5 was no good for BlueSCSI. Tried a pre-built image of 6.0.8 in my SE with BlueSCSI and it worked, plugged 6.0.8 in to SE/30 #2 and it booted up so fast. Stoked! TechStep kept saying everything was fine with the SCSI system, I was even able to connect...
