Nice find!
After reviewing that article, I took note that John Bass says his software really only handles drives up to 5MB, suggesting additional software to partition the drive if you go beyond 5MB to keep the sheer number of files from bogging down the system.
I don't know if there ever was a file. If there was, I was stupid for not having downloaded it back in 2009 when this thread was started. I spent a lot of time Googling for it recently but came up with nothing. Hopefully someone can provide it. I hate it when useful information resources...
Well, I finally got my 800K Recap & Lube video published today. Thanks again to @LaPorta for your video which helped me. I will show the EM-30L in a future video after that arrives — thanks again, @jjclay! This video is packed with info. Enjoy.
I'd love to have a schematic of those video cards to find out! The company who made it is long gone, but it would be nice of the IP owners or engineers at the time could donate technical documents to the vintage Mac community. Rebuilding the schematic isn't impossible, but it takes more time...
Will, do you have a multimeter to test the voltage coming out of your step-down converter? And is the frequency of 60Hz correct too? Even if the voltage and frequency are correct, what happens when you connect another 120VAC device (other than your Mac) into that converter? I am trying to...
@LaPorta
Thank you. I just finished watching the entire video.
You mentioned that you have broken off the two little plastic tabs that secure the metal cover underneath the gear box in the past. I am curious as to your exact method of repair since I have the same problem.
Right now, I have...
@jjclay
I too thought the gears might just pull out, but I could only get the little yellow gear and the white one above it out by gently pulling. I didn't try to apply too much pressure to the other two bigger gears for fear of breaking them, so I look forward to hear the technique you employ...
@jjclay
Thank you for your kind offer! It is truly unfortunate that EM-30L is not sold here in Japan. You might want to check with your local post office to see if they will even allow you to ship it. Post offices around the globe have gone made in restricting things they deem "dangerous."...
But if a component was shorted and therefore burned and destroyed, the ejection should stop working completely. In my case, it works sometimes and other times not. I am basically trying to figure out why.
Well, it's impossible for me to buy Molykote here in Japan insofar as I am not going to buy a $100 bucket of the stuff to satisfy my curiosity. Maybe someone will donate a jar to my YouTube channel one day for me to make a detailed comparison because I am curious about the difference with my...
Not available in "small jars" on Amazon Japan though. :-( It is sold, but only in paint bucket size tubs for about US$100 equivalent.
But the bigger question in my mind is, what's the difference between that EM-30L and White Silicone Grease? Both play well with plastics. And the fact is, I...
@jjclay
I’m glad my lube video was a help to you. I would certainly appreciate having a look at your video!
I am curious about the grease or oil on those gears. A lot of people use lithium grease when lubing drive metal parts, and from what I understand the original grease was also lithium...
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...
I have yet another bad 400K floppy drive about which I made a short video below. I am curious about the above post from @pbertolo, whether I should touch that particular screw or not. I'm also curious about the direction it allows the that small PCB to slide. Sliding it only 0.1875mm in...
@olePigeon, based on the excellent links @sfiera provided, it would seem that only particular SONY floppy drives work, and then a lot depends on how the media was stored through the years.
@pcamen
Applesauce costs $285 for the version we would need to archive Mac disks, and honestly the only reason I am even investigating Kryoflux is because a kind Subscriber to my YouTube channel donated the Kryoflux unit (which is valued at about $100+shipping).
Someone in the Kryoflux...
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...
Regarding the ribbon cable, it's important to consider that I am using the same cable for the internal drive. Yet, when I swapped drives, then the both started working. If the cable was an issue, I would expect to see the same problem on the internal drive even after I swapped drives...
