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...

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!

I have been exchanging dialog with a viewer of my YouTube channel who has been servicing his 800K drives in conjunction with my video on that subject.  In particular, he has two 800K drives which show the head moving all the way to the back but then the heads stay there. If the head is then...

There are times when you want to make a very long, custom cable so as to pull the SE/30 motherboard outside the chassis for easier testing while still being able to power up the machine.  Until now I've been soldering wires onto testing points and pulling those wires outside the chassis, but...

First, I'd like to thank @ttb, @aeberbach and others who contributed to my separate thread on SE/30 SONY Chip Voltages.  The conclusion of that thread is that while most of the 47uF capacitors on the motherboard see only 5v, there are 4 which see about 12V.  That is actually a problem for those...

Have any of you ever measured voltages at UB10 or UB11 (Sony chips) on an SE/30 motherboard?  I don't have a long enough cable to safely pull out the motherboard to test that.  I am specifically curious if capacitors C3, C4 & C5 see a maximum of 5V or 12V.  I suspect one or more of those...

Think the Macintosh 128K, 512K & Plus motherboards don't need a recap?  Time to Think Different.  It's been 35+ years since the debut of the 128K & 512K, folks.  Fluid-filled capacitors don't have eternal life. Properly chosen solid Tantalum, on the other hand, will last the life of the...

Do any of you own a Mac Plus extended keyboard with numeric keypad? Could you please confirm the capacitance & voltage ratings of axial capacitors C1 & C3 shown in the photo below?  I think there are only those 2 electrolytic capacitors, but if there are more, please ket me know that...

A viewer of my YouTube channel recently asked me about a Sad Mac Error code that he is seeing on his Macintosh 128K: 047A80 It would seem to be RAM related as per this: To identify the individual bad chips, we use this... Unless I am in error, the 7A80 part would seem to indicate 6 bad...

I was going to post the video below yesterday, but this forum was down.  The topic really doesn't fit perfectly into "Peripherals" because every old Mac has a floppy drive, but I just decided to put it here in hopes this category is the closest fit.  Those of you on FaceBook or who are already...

Until now, I've been using 400K, 800K and HD20 Mode dsk images with my FloppyEMU without problem.  Today, I tried to use a 1440K image without success.  I extracted it from the Blanks here.  When I boot off my SCSI HDD into System 7.1 on my SE/30, it can't read the 1440K disk and asks me to...

I am currently editing a forthcoming video on the Apple Hard Disk 20SC. The SCSI drive mechanism I use with my 20SC enclosure is not stock, so I am curious about the sound of the stock drives. Would any of you 20SC owners who still have the stock 5.25" Seagate ST-225N drive (photo below) be...

I have a Hard Disk 20SC external SCSI drive enclosure that has a SCSI ID selector switch on back.  Because I am using a non-stock IBM DGHS 4.5GB drive inside, I've left the SCSI ID select switch cable disconnected.  But I am eager to change the SCSI ID on the fly.   Here's a photo of the drive...

Folks, let me be clear.  MacEffects is worthy of your consideration.

As many of you know, there is a small eject gear in 800k floppy drives which often breaks, and I've seen some replacements sold on EBAY.  The only auction I could find with a reasonable price for the gear and reasonable international shipping (to Japan, in my case) is this: PMMA plastic in...

A very kind subscriber to my YouTube channel donated a Kryoflux.  It hasn't yet arrived, but I am now thinking about how best to use it to make archives of Mac 400K and 800K disks.  One thing I see in YouTube videos on the subject is that everybody is using some kind of PC floppy drive with it...

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

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...

Do any of you have the original printed documentation that came with Apple's M0130 external 400K floppy drives? I cannot find a scanned copy anywhere online.
