@MOS8_030 & @pbertolo I just removed my "bad" internal drive and connected it as an external, putting my external drive mechanism internal.  Now both drives work fine.  Please watch this short video.  I would appreciate hearing your thoughts!

It's important to keep in mind that the Macintosh 128K, 512K and even the Plus did not have an internal fan, so all the caps are running hot.   Even when running those machines on a cool day, about an hour after you've switched on power, if you put your hand above the air vents that are above...

I only used the "Error Rate Test" window, so I assume you are referring to a control on one of the other two windows? I was afraid to click "recalibrate" for fear it would write something to the drive's firmware that I later could not correct.  Do you know exactly what it does? By the way, my...

Thank you.  I am able to get both of those images to boot my Mac 512K using my FloppyEMU.  But let it be known that they will NOT boot Mini vMac.  You get weird lines on the display in Mini vMac. I also get the same "apparent freeze" in Sony Test on both of your images; HOWEVER, the key is to...

Hmmm... Lots of views of this thread, but no replies.  Well, perhaps I can stimulate the discussion with some 400K drive schematics a friend emailed to me today.  It seems to closely match the big PCB shown here.  Even so, there are differences.  For example, the schematic mentions IC106, but if...

I’ve had no success with the image on Macintosh Garden. I see in your video though that you have two working disks. Could you please make a disk image of each of your disks, ZIP them, upload to the cloud and then provide a download link here?

@Crutch The answers that @LaPorta gave or exactly what I would recommend, specifically using Mini vMac to make the appropriate image. But I would also strongly recommend the FloppyEMU. It’s been a lifesaver for me!

I have not removed the felt pad because I worry I might tear it or damage it, and since I don’t have a replacement, that’s a legitimate concern. I have not cleaned the felt pad, because I honestly don’t know how to clean it properly. However, I have cleaned the head using a swab and 100% ISO...

Here's an Unlisted video I just shot on my iPhone and uploaded to YouTube to make it abundantly clear the trouble I am having: https://youtu.be/exVioW6vrgY Hopefully this level of detail will help some of you to better understand the problem I have, which again affects Mini vMac too. Download...

@MOS8_030 If you have a look at page 36 of this SONY 400K Drive document, you will see they have a specialized "inspection module" used to test that version of the drive.  Apple's version is similar but not exactly the same, so I don't know if the same inspection module is required to use SONY...

@tt Thank you for your kind words.  My first "public" video on YouTube was way back in 2007.  But it was low resolution and had no text or voice-over. (The Mac shown in that 2007 video is the same one you see in my new 400K recapping video, and the same Mac I used in my Analog Board recapping...

@MOS8_030 Thank you for the feedback.  My HyperDrive 512K (which I am not currently using to test) has the newer "B" 64K ROMs.  My other 512K, which I am using right now to diagnose a 400K internal drive, has the older version "A" 64K ROMs.  I believe the only difference between A & B is...

@pbertolo I finally made time today to play with SONY TEST 6.9 (downloaded here) & 7.0 (downloaded here).  Sadly, there are big problems: 1. I cannot boot from either image, neither in Mini vMac, nor from a Mac 512K with 64K ROMS. 2. The IMG containing version 6.9 is totally stripped of...

@maceffects I am truly humbled by your kindness.  I just sent you a personal email offering you my sincere thanks.  In light of that kind contribution, I would feel guilty taking a free case from you.  However, it would indeed open the door to a video review of your enclosure, especially since...

@maceffects Thank you for your kind words both here and in the comments section under my video.  And as I mentioned in my reply on YouTube, I appreciate the hard work you invested into making some great injection molded cases for old Macs and the Apple II! Most people who've never manufactured...

Yes, even 400K floppy drives need to be recapped.  This video walkthrough holds your hand through the process.  I show a few clips of Epyx Winter Games at the end.  The bootable 400K DSK image I created yesterday is now on Macintosh Garden.   https://youtu.be/71Lz9OjJFe8

Thanks, I will contact him. It probably will work on an 800K disk, but I didn't test that.  The game originally came on a 400K floppy so that is what I tested with.  I don't have my 128K motherboard anymore, but apparently it will work on that Mac too.  I tested it with my Mac512. I appreciate...

Thank you very much, that suggestion works!  I now have a perfect copy on floppy disk that no long complaints that it is unauthorized.  So it's clear the copy on Macintosh Garden, at least, the main application program, was modified somehow. Yipee!  You're a great help, @LaPorta! HOWEVER...

It's quite fascinating to me that Epyx Winter Games has been on Macintosh Garden since 2009 and yet nobody appears to have gotten it to work. I still have an original copy of Winter Games on 3.5" disk for the Mac that was purchased by me back in 1985.  It boots my Mac512 just fine, and all the...
