    PM 7300/7500/7600/8500/9500 PSU Pinouts?

    IIRC they changed it with the 7300. The 7600 is identical to the 7500 in every way except for the CPU card and the badge. The logic board and PSU are the same. Of course the configurations options are different.

    PM 7300/7500/7600/8500/9500 PSU Pinouts?

    I think the 7200 PSU has the same pinout too. I remember back when it was a thing, I bought an upgrade kit from Apple to upgrade my 7200/75 to a 7600. It included a new logic board, CPU daughter card and video input/output board. I do not believe it included a PSU and the stock 7200 PSU was used. That was 20+ years ago so I could be wrong but that is what I remember. I found the receipt for it recently in some old papers and it lists logic board but no PSU so I am reasonably sure about it. Here is a website that appears to have a pinout of the connector: https://modelrail.otenko.com/apple/power-mac-7200-power-supply

    Another Laserwriter

    No, I guess I am a nut too. I still have an old Samsung Laser Printer circa 2000 that has Epson emulation so it works with everything, I also have an Epson LQ 590 Dot matrix (Recent model), A star NX-1000C Rainbow, Star NX-2420 Rainbow, StyleWriter 2400 and a couple of USB Canon bubble jets that use the same ink tanks as the StyleWriter (not surprising since the StyleWriters were mostly Canon mechanisms). I don't yet have any LaserWriter printers and I would like to have one but am out of room as printers take up a lot of space.

    Performa 200 - Original Loaded Software?

    I just recently recapped a Performa 200. I will have to look on the hard drive. I am pretty sure it has the original software, outside of someone upgrading it to System 7.5 but I know it has Claris Works on it. I will check. Does the Apple Legacy CD-ROM have the disk images on it? I have used that to get the original software for my LC, and IIsi.

    How to make disks for a IIGS?

    Cool. Thanks for the info. This is the first Apple II I have ever owned. I used them in high school but that was the extent.

    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.

    System Saver And Hard Drive Enclosure

    Thanks. Yeah I was amazed too because I usually don't find anything at the thrift store. Sometimes that thrift store prices things ridiculously expensive and sometimes you find deals. So were these form factors meant to go underneath compact macs? Interesting. It does indeed look identical.

    System Saver And Hard Drive Enclosure

    I was in a thrift store today and saw a case with a SCSI terminator and cable hanging off the back. It turned out to be an APS hard drive in a somewhat similar size case to yours. I turned it on and the HD does indeed spin-up. Not sure what size it is but it is a Quantum Pro drive. Different styling but similar to that posted by the OP. The warranty seals were in tact so when I opened it, it was nice to see the drive with the resister packs taped to the top of the drive. I haven't hooked it to a Mac yet to see what is on it or if it actually works but I will hopefully this weekend. For $5 it was worth the risk. I don't know anything about this drive but I do know it was made circa 1993, at least the FCC ID was registered in 1993, July. Anyways, didn't mean to highjack your thread but seeing it made me think of your find.

    SCSI2SD external cable type?

    Glad you got it working. Like @tanaquil mentioned, I would also make a smaller drive. Start with something smaller like 500MB and see if that works.

    PoweMac 7200, PowerMac G4, various books

    Nice finds. The 7200/75 was my first personal Mac, in late 1995. Great machine.

    SCSI2SD external cable type?

    Hello, I would try some other combinations of name/ID. Apparently they have to be exact. I know Seagate works as most, if not all of my Seagate SCSI drives are seen by the Disk Tools and Drive Setup apps without patching. As for the Cable, yes you will need a DB25 to DB25 SCSI cable. Zip drives, and other devices used this cable. Also the V5.1 has a terminator that is software controllable. Did you configure the termination?
