    How to make disks for a IIGS?

    Hmm. Mine is the A9M0106. Weird it is 800k model but the label on the drive says 1.4MB. I haven't opened it in a while. Do these drives also work with Macs that have an external floppy drive connector?

    How to make disks for a IIGS?

    I have a picture of it on my MacBook here so I have attached it so you can see the front of the drive. I don't have a picture of the model number, though. I will check it when I get home.

    How to make disks for a IIGS?

    I have a variety of Macs that can write images back to floppy. I mainly use a Beige G3 desktop for that because it has a decent sized HD and USB. I wrote my IIGS disks using that. Curious though, my Apple IIGS floppy drive says 1.4MB near the eject. It is an Apple drive but it only reads 800k. Didn't Apple sell an interface board that you had to plug the 1.4MB drives into because the built in one can never work with a full 1.4? IIRC that is the expensive part. I could be wrong because I was never really into Apple that much until later on.

    Macintosh II - Revival and overhaul

    Polymer caps will be better because, as you say they don't leak. I have found that some are rated for very high hours life but some are not. Usually they have a rating like 5000 hours @ 105c. I have seen some that are rated for 10-15,000 hours. But it seems usually they are in the 2000-5000 range. My last few recaps I have been using high quality electrolytic that are rated for 10,000 hours. They are 1/3 the price, or more, of the Polymer caps. The also have hybrid caps too. As far as I understand they are functionally equivalent to electrolytic caps, so you should be good. Of course, just because it is rated for so many hours doesn't mean it is going to only last that long. The ratings are if the cap is operated at that constant temperature. Most of the caps in Macs, (with exception to those near the power supply or CRT iMac caps) will not get anywhere close to that temperature and will usually be cool to the touch. So that means that they will last many more times longer then what they are rated. I think also this is why many people that do recaps use tantalum. They won't leak either. I, however, always do like for like.

    Macintosh II - Revival and overhaul

    I love it when they are all the same! The PM6100 is the same 47uf caps too. I looked at the picture and that is exactly what I thought it would be because they looked the same in my situation.

    Bolles finds

    NIce finds. Maxell, more like Maxhell. I guess it is not surprising that a media company doesn't know how to make batteries, if they even actually made them to start with vs relabel some cheap crap.

    Macintosh II - Revival and overhaul

    I see the corrosion on the IC legs next to the SMD cap in the close up but it doesn't look bad to me. It probably just needs a cleanup with a brush and some Isoprop. This board looks in much better condition then the Classic II I just re-capped, if that is any reassurance, and after re-cap and cleanup it now works fine. As for the batteries, I don't know much about the Mac II but aren't these the same 3.6v batteries as just about every other Mac but soldered directly? If so check the measurements for this part: https://www.digikey.com/short/jd8772 See if those battery holders will work then just use the regular 1/2AA battery that we always use. If they don't matchup you could just install wires between the board and the holder and velcro the hoders someplace. I did this with a G3 Tower that had a corroded battery and I needed to replace and relocate the battery holder. It also gets it off the logic board so if for some reason it ever leaked the board would be safe.

    Macintosh Plus White bars issue

    I wouldn't dismiss the capacitors so quickly. They can look clean and not bulged but still be out of spec or shorted dead. I have never had one of these to repair but my understanding is there is a lot of heat generated from the analog board and the life of those caps are shortened because of that. That said, voltages should be something to check. This video shows a Classic II but the screen looks similar (caused by caps): https://youtu.be/mBnQXqRjrCc Of course, the Classic used SMD caps and they are much more likely to leak then the 30 year old through-hole caps in the older Macs.

    System Saver And Hard Drive Enclosure

    I have found several old HDs over the years and found all sorts of interesting things on them. This is the first SCSI HD I have found that was in this form factor for the compact Macs as I was never really a compact Mac user. I didn't like B&W computers at all in those days. I will image it as is though before I format it.

    System Saver And Hard Drive Enclosure

    I just hooked it up to the Classic II and low and behold it popped up on the desktop, after system software 7.5 updated the driver and rebuilt the database. It didn't have very much on it. Best I can tell it was used with something that had System 6.05 on it as there is a system folder. It is the 170MB model and it has 150MB free so it only had a little over 10MB used. There was a copy of Write Now 4.0 and about 10 personal documents with someones list of stocks and assets and other stuff. Looks like it was last used in 1997. Since the docs have BOB in the names I assume it is Bob's old docs. I am going to browse the system folder to see if there is anything good in there but personal docs will get deleted. I haven't browsed all the folders yet but since it was a boot drive and the system software is pretty small in size I would say it was used with some model of a Compact Mac.

    System Saver And Hard Drive Enclosure

    I don't know yet. I got side tracked today on helping someone so I just now got finished recapping the Classic II. Hey sound works again. I will try to hook it up tomorrow. I only know that it powers up and the drive spins up. I don't know if anything is on it or not. I will for sure check for treasures. The Classic II I got still has the original owners files on it, even some custom recorded alert sounds with him talking about an error. funny stuff. I'll let you know what I find.

    System Saver And Hard Drive Enclosure

    Yeah, it is very similar. I think it is a bit more sleek compared to the previous compacts like the SE/30, etc. But I am pretty sure the dimensions are pretty much the same.

    System Saver And Hard Drive Enclosure

    Yeah, It does have the weird paint just another color. What is it a metalized paint for interference or something like that? As for what I am going to hook it to I have a few Macs that I could use to test it. IIsi, LC III, 7200, 8600, etc. I actually recently purchased a Performa 200 aka Mac Classic II with orginal 80MB HD. It is my first Compact Mac. It seems to work, although I didn't hear any sound. I am not even sure where the speaker is on those guys. I took it apart and the logic board has leakage from the caps. I removed the caps a few minutes ago and will clean up the pads and solder on new ones tomorrow. I cleaned the board with some Isopropyl alcohol. and hopefully the sound will come back when I am done re-capping it. Anyway, I thought about using it with that Mac, it would be period correct and all.

    System Saver And Hard Drive Enclosure

    That's kind of what I figured. I never owned a Compact Mac. My first Mac was a 7200. My family had the original Macintosh but I was not really into it then as we had a C64 and that was more my thing. I do find all these devices pretty cool though. @MacintoshMan1999 Yes my case is plastic. But it seems pretty sturdy. I am going to hook it up tomorrow and see if it is functioning. From what can tell from the ads of the time, it is a Quantum ProDrive ELS which were low power and pretty small. I think between 40 - 170MB.
