    Macintosh IIsi display issues.

    I had the same problem and for me it was indeed the adapter I had. As pointed out you need a monitor that supports Sync on Green but you also need to make sure the adapter supports SOG too. I have a Sony CPD 17" that does support it and it came with and Mac adapter that does not. Sony monitors were popular with Macs back in the day. NEC also made monitors that seem to support Mac on some models. The adapter I ended up digging up was one that had dip switches and specifically supported Sync on Green.

    $30 LCII from eBay

    Yeah, Not too bad. Nothing a little IPA can't fix. The last Mac I recapped was a Classic II and it had gook all over the board.

    Demand for Performa 630CD?

    The nice thing about the 630/640 is that it has IDE. So you can replace the HD with an IDE to SD or CF card. If you like spinning drives, like I do, it is not too hard to get older IDE drives. On that note, I finally found an original 640CD restore CD. I know you can download one now from various sources but I like to have the original software to a system if I can.
  4. If this is the same keyboard that came with the iMacs and Blue and White G3, the small size keyboard, then there are clips all the way around the front, sides and IIRC one or two in the back. They are like latches and they are super easy to break trying to unhook them. If they break then the two halves will not stay closed. You have to carefully push in with a plastic pick or separator and push in the right spot while pushing upward to unhook the latch.
  5. Just for fun, I have tried several different IDE to SD and IDE to Compact Flash adapters and have found them to be pretty decent, depending on the card you use. Semi-Fast SD cards (UHS-1) are pretty cheap these days. I bought a Sandisk 128GB microSD card for $30 at BestBuy yesterday for my Nintendo Switch. I have seen them even cheaper then that. The IDE interface in those era computers will not take full advantage of the 100MB/s speed but it will be faster then an HD in most cases. I have found them to be a decent replacement for HDs. Just a thought...

    Figuring out dead PowerMac 6100

    For sure. I recently recapped a 6100 where the caps were literally falling off the board at the slightest touch. The thing is it worked fine a year ago. I also have an 8100 and I checked the caps on that board and they are not showing any signs of leakage or corrosion as the solder joints are still shiny. I will still recap it within this year though, just to be safe. Those were made in 1994 so next up would be my 7200 or 640CD, although neither of those show any leakage or even a hint of corrosion.

    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.
