The 1541s natural state is for the drive to be spinning and the computer built into the drive has to be executing code in order for it to stop. A spinning drive with a red light is much like a black screen of death on a C64 (i.e. its just not running). Like the C64 this can be caused by a lot of things but, since you have no lights, I would start by checking the voltages. For detailed troubleshooting for the 1541 I highly recommend Ray Carlson's fix file found at portcommodore.com/rcarlsen/cbm/1541/fix1541.txt

@@RavenWolfRetroTech thanks sooo much mate!

I think that's the MSD SD-2, CMD never made a 5.25" drive.

I will show it in the next video which I am working on as we speak. I was hoping for Sunday but the CRT has a leaky cap so I am going to have to add in a recap. Once the CRT is removed from the case there are 3 clips that can be removed which will free the front glass!

Great! Yeah, I am hoping that all I need to do is to take off the top and bottom covers, then I can remove the front panel, then the glass of the crt without disturbing anything else. But at some point, sounds like I should also probably inspect for leaky caps too, sigh.

Once the top cover is off its just 4 screws and a few connectors. Then the CRT just lifts out, no need to remove the front or bottom covers IIRC. As for the caps I was really surprised to find one leaking as the caps from this era are pretty reliable. You may find that you are just fine.

Lol, I work on it almost daily but it's a huge project. I'm pleased with the progress so far.

haha, I can tell this looks like the dwarf fortress. But man time flies doesn't it

Thanks InsaneDruid! Alex from Reviving Retro also emailed me a picture . I am going to check the 2 SX-64s from the Stone Collection to see if any are that style and include it in the next video when I get back from a family reunion I am at right now. If none are that style I will have to see if I can get some good angles of the drive removal process somewhere.

I was in the process of organizing all the Stone Collection materials when I was interrupted by allergies, followed by a family reunion. I I will be back on it this month and have been putting the extreme items aside.

@@RavenWolfRetroTech I found a guy in Poland a while back that had a rig he sold you could plug into the USB port on your laptop, run the software and burn disk images to a 1541 5 1/4 floppy. I have some of the SD emulator stuff, but I prefer to use the 1541 with a fastload cartridge so I can save my data. A lot of the emulator and games make it very hard to play with multiple disks or saves.

@@jamesmaddox40 I used a ZoomFloppy to recover my DDM files on the PC so I could run it in VICE a few years ago. It was pretty funny using a 170k serial floppy on a modern PC.

@@RavenWolfRetroTech Awesome floppy note. My son in law bought me some 8 in h floppies at a yard sale new in the boxes. I don't even own an 8 inch floppy drive yet, but you know I'm gonna buy one just because he did it. I'll have to pick up a PC too cause you know they match. Lol

man, how's your back? My dual 8" drive weighs in at over 60 lbs!

Doh, UA-cam ate my reply so here's a synopsis... Jiffy Dos - This has become non-optional for me. The speed is nice but the ease of use is invaluable. I love the puzzle solving of a repair so I am good with issues. I have plenty of PLAs due to a friend making new ones from NoS S100 chips which are more reliable than the CBM ones. I do constantly find myself short on 6526 CIAs and VIC-IIs though. I always had to sell my old gear to afford the new stuff so I too had to start finding the replacements online. The Stone collection kinda blew that out of the water for 8-bit stuff and the KPTV Amigas fixed me up for the Amiga. The only thing I really need to revisit one day - but not too soon - is the Apple II and SOL-20

@@RavenWolfRetroTech Never could afford the Apple II back in the day. That however is what I trained on in High School.. Apple II Plus, and Apple II E. I finally scooped up an Apple II with a working Orangish screen color for the text. The ones above had the greenish tint. I also had a couple Floppy Disk boxes of Software shipped separately from of all places an actual shipping port with boats. The USPS promptly lost the software never to be found, but to my surprise the Apple II loaded it's home screen and after turning knobs on the monitor to brighten the text I found the computer and monitor worked. I still have my programs disks from class in 1985. I had written a 3D rotation of a stick figure pyramid back then. I was so proud. I think I finally picked up the DOS software for the 5 1/4 floppy drive. I got so excited I forgot the mention that I got maybe 2 drives if I'm remembering right.

As a consumer this is correct. Improper cleaning could cause damage and there are high voltages in the drive that could cause injury to the unaware. I do use a cleaning diskette regularly, However, the proper way to clean a drive by a technician when servicing is with a swab and alcohol. In fact, in my floppy disk cleaning video there are some instances where the cleaning disk would not clean the heads and even a swab took several minutes to remove the severe contamination from bad disks.

Thanks Frank!

Thank You Bruce! Just Bruce!

Thanks RacerX! Keep an eye out and I bet they find their way to you.

At todays prices for sure, at the time they were a lot more reasonable in this area... albeit without the extra "Parts Machine" which I really want to find a way to restore!

I will check the caps in the next video but, based on what I saw, I expect that they are fine. I'm in Oregon so my machines are all NTSC.

Thanks Donald!

Thanks Mr. Cake 😎

Lol, thanks Bro!

Thanks!

Hey there James, I love the automatic proof reader when it came out. We always had to debug the typed in programs and, since I started without any way to save, if the power went out all was lost. BTW, It looks like this comment got caught in the UA-cam filter due to links so that's why I took so long to notice it, sorry. I generally don't approve those just because of the spammers and the fact that I have to check each link but, since I saw it was you I went ahead and let it through.

It's been a while since this one and I'm traveling right now but typically i don't disconnect anything that would affect alignment unless i have to. Mac drives usually just need cleaning, lube, and an eject gear...

It can emulate several floppy drives including 1541, 1571, & 1581. Each disk takes one of the 254 partitions though so you can do a lot but not unlimited.

Thanks Frank!

You can bet I was washing my hands a lot Doug!

That would be the recent "Pimping the 128D" video. It is not a step by step walk through though because I had a ton of issues getting the Zulu SCSI to work with the CMD-20 and, in the end, I was not sure why it started working for me (although I have my suspicion as mentioned in the video)

Hey Alex! I actually had a mention of using the ultrasonic cleaner in my footage but I cut it because its really only good for getting the dust out of the underside. We used an ultrasonic cleaner in my business for a couple decades and we learned early on that plastic can easily be pitted by excessive run times. I have run them before for about 6 minutes but that only made the cleaning slightly easier so I cut the footage since most people don't have an ultrasonic cleaner. I know what you mean about it being a bit of a chore. I wasn't kidding about the cleaning in front of the TV with the wife and the dogs. I still never found that lost screw!

Thanks, will do!

Thanks! It did turn out better than I expected

Thanks Rudy!

Wow, thanks!

I have the fix it itch today but could not decide what to work on so, once I finish some chores and some work on DDM, You decided for me!

Sadly, because I moved to the Amiga in 1988, Most of my disks were lost (I was in the Army at the time). Fortunately one box of about 10 disks was saved including my DDM source code and they all read fine. Funny enough if you saw my earlier video (2020?) where I thought the back sides were bad on a couple, I later realized that they were written on my C128/1571 using a little KERNAL hack I had created (called Duo-Drive) that let me use side one as device 8 and side 2 as device 9 in 64 mode, so they cannot be flipped in a 1541 as they are spinning backwards.

@@RavenWolfRetroTech that's a shame. I wish I still had all my shoeboxes of disks

Thank you!

William, I have been trying to reach you on your order. can you reach out through the email on the order please?

@@RavenWolfRetroTech thanks! I just replied to your email.

I will look into cyclomethicone as I was wondering if there was a good way to lubricate the jacket sleeve😅😎🤓 This is a well worded Compliment sandwich! Many internet users could learn a lot from this post on how to correct someone without trolling! Seriously, Thank you for the corrections.

@@RavenWolfRetroTech Occupational hazard of having a minor amount of OCD ;⁠-⁠) but also understanding the work that goes into this kind of experiment, and also the production of a UA-cam video. Thanks for being understanding :⁠-⁠) and I truly am looking forward to your next videos, and I am subscribed.

Remember that in a list of questions, every other one is odd! Even if the speed is similar, I really love the abbreviated syntax for DOS commands in JiffyDOS. Besides that I have the HD-20 and RAMLink that support JiffyDOS and I don't think I would do well using different command syntaxes for some drives. Then there is the elephant in the room! We all know that most 128s spend the majority of their lives in 64 mode. Back in the day I used 128 mode for 80-column text editing (With Word Writer 128) and Assembly coding (With the LADS assembler). Even then the code I was writing would only run in 64 mode as would most of the software and games I owned,

March-in-tosh is an annual event each March, focusing on Macs much like DoScember

@@RavenWolfRetroTech ah, I see, apologies, apologies 👍

Wow I am surprised that worked. I had to look up that drive and I see that it is the same as the Excelerator+. Oceanic was right here in Springfield, just a few mile from my home!

Thanks Frank!

Thanks RacerX. I have not tried the 1571 with my ZoomFloppy, just a 1541. I'll give it a try. I have noticed that magazine disks are usually very low quality and have had terrible recovery rates with them

@@RavenWolfRetroTech Yes I have found the same. Though I have some exceptions it seems the disks they used were not great. Especially true for the Loadstar disks in the newer issues of the early to late 90s. I can usually tell by looking at the jacket what kind of disk it is. The ones with circular rivet marks seem to be better and the ones with no rivet marks on the back seem to be Athana. Their early first 2 years or so they used Opus disks (they actually were a reseller too) and I found these did not hold up. If you open the disk you will see the liner has turned mostly brown. To me this is the liner going bad either from excessive heat or chemicals I am not sure. But I do have duplicates of some issues from collections that were stored at room temperature and some of them are fine. The liner is saturated with some kind of lubricant. So perhaps that lubricant on some brands turns bad after time? Also I have found that the 1571 in particular is very sensitive about junk on the disk. The squeal sound you showed I have heard all too many times and usually like you,I find the disk now has grooves on it. Using a 1541 though I have really not found that to be an issue. I am guessing since the 1571 has 2 heads there is more touching the disk vs the 1541 that has a felt pad on the top that actually seems to clean the disk a tad bit. I have noticed that if I image a disk that shows errors then do the backside often it is fine. Then if I flip the disk again to do the front it comes out fine. I guess it has to do with the felt pad sweeping away some minor crud. The 1571 just collects it in the grooves of the heads. Anyway if you ever need someone to test something or bounce ideas off for this stuff, please feel free to contact me.

And they would want to know why they are cleaning save icons :-)

I have passed a few boxes of user disks, along with some MECC disks and magazine disks, on to members of PDX Retro Forest and am going to have a way for Patrons to get them for the cost of shipping... With DDM taking a ton of time over the last year I have been feeling like I need to get them to people that will enjoy them more. Right now they take a ton of space in my storage shed and, while dry, are still deteriorating as time passes.

I was thinking I would start by just putting some bad ones in my attic for a while. It is very dry and the attic fan keeps the temp below about 120 in the summer. I don't have a food dehydrator so my options are limited.

Wow, thanks!
