Currently 110 views of this thread but the only replies are mine.  Surely one among us must own a floppy drive and have seen something similar.  If so, I want to hear from you! Thank you!

The more I ponder this problem, the more it bothers me.  I don't see how it can be the Zero Track Alignment problem.  If it was that, I would expect the head to stop it's repetitive motion when the head was manually moved forward and then a tool was inserted into the optical sensor (see the...

I've been speaking to a gentleman in the comments section under one of my YouTube videos about his 800K floppy drive, and today he shared a video of his problematic clicking head with me here: As you can see, the optical sensor is in fact working fine.  If it was dirty or clogged, it would...

Answer: The thickest wire that can be used to fit the terminals in a compatible connector.  As such, I do not believe you can go thicker than the stock 18AWG wire.  If you could, that would be great.  The thicker the better, especially for an upgraded SE/30.

I had the same problem until I checked the main wire harness that connects the Analog board to the motherboard.  A couple wires were higher resistance than they should have been.  Since I didn't have the required terminals to merely swap out the wires, I soldered on a wire in parallel with each...

It is now February 2021. One year has passed. What is the pricing and availability on this WIFI kit, and is it being made available separately or included with a MacCon Ethernet Clone?  Is the kit 100% complete, including the needed antennae pair? And just to reconfirm, it is only possible to...

Here's the Mouser Cart I used to recap my 1.44MB floppy drive.

Thank you. I put Mouser Carts in the text description of all my videos.   I also try to post links to my videos here and in other places where vintage Mac users get together and chat, but  there are still a lot of folks who haven't found those videos.  For the sake of curiosity, did you search...

Thank you for sharing your recapping success story, @Rjp663!  That's great to hear!

I'd like to thank @maceffects for bringing it to my attention that the HP 12c financial calculator DA was not on Macintosh Garden. I just now uploaded Demo version 1.1. Mark also let me know that a Version 2.0 from 1990 existed too.  If any of you know who won this EBAY auction, it would be...

No electrolytic capacitor is immune to the ravages of age, folks!

No one responded, so I look forward to your test results this weekend! :-)   No doubt you'll confirm what I show in my video.  I doubt the unit I have is unique.

Well, I'm not going to take out the SEASONIC from my SONY PSU chassis only to blast it under no load with a hairdryer.  But back in 2018 I made the video below which serves to better explain what I said in my previous post, showing very clearly that "high current" does not appear to trigger the fan.

I mention the model number at 10:20 in my video. My model matches yours. Regardless of what the specs say, I am hearing the fan turn on after the Mac has been on for a little while.  I've not measured the current consumption of my entire Mac, but I highly doubt it draws substantially less...

The following is the advice I offered to the individual who commented on my YouTube Channel (Track Zero Alignment): https://bit.ly/3cnyKbr https://bit.ly/3tczCGa Search this PDF for "Verify the disk drive's general operating" to jump to the right section...
