    SE/30 Logic Board Resurrection

    Sorry guys, hot air station is actually "858D." https://www.ebay.com/itm/858D-Soldering-Rework-Station-Hot-Air-Gun-Kit-Iron-Solder-Holder-Tool-w-Nozzles/192961707800?epid=18019765421&_trkparms=ispr%3D1&hash=item2ced69ff18:g:2oUAAOSw94Ba9Qca&enc=AQAEAAAB0BPxNw%2BVj6nta7CKEs3N0qX4K02bYzcYuPEEGtp2%2FJJmFmhUtIxmXhumSbzu%2BTVerItQp7ORTPat5Ed0vYnDm2eyIdB9zIBk%2BRoO0FnqxOTOCaAsZjEFIOwtZA6JPAnjMWEkl6XKz6wSH40shhkqwbC%2BnsYimOmzlHjG5zZZjxgtOi0di46QkR92nPtSEBnQZ8p0HKeKn49JmPezt6j1B%2BNUek9j94BP8CSnf1FOQCaEvmuRjVeD7FJ3QMDCTxknRQ826FVatyRF%2Fag5UEex45YzEzTlTHTVLIWontTUUCLQm3HtEmrOxRTvIO1ULoS5VMGLANjmiZsW7OT7gt0k%2BO2%2B7MkLsxKEZ3cCi9AG9tTmOXnKYst1AiysnTN%2FvAw9nelJWMw82XtHPEX5%2FbZqGNUoTm3CDpkwu4%2B1kI%2FuiiQ%2FvVxvpkMoGG6xrO3Z%2F1Z7uYE%2FxJ8KZvgkAKzOfoB%2FuSat58%2FdmLtnnl4tn1IxDmwrokgZxY%2BmZ3ZCvK0i%2F7TyRJFUEkzY3aSyiyukYgaxBNemxEDMH3hoehZG5Mdp6%2Fg9JdNWoCq8YEXRMvusfywQPatvdvF5ou9M5ltVlWT%2BbwrvstSoq4d9FTPIYuRIy4Me&checksum=192961707800c51cb467100143988c071a0f3c4932ef
  2. I read about one case with the Macintosh TV where cap goo had shorted a reset switch on the board, and that was keeping the board from booting. Not sure if yours has the switch or not, but that could be an easy thing to check.

    SE/30 Logic Board Resurrection

    LaPorta, If you're still looking for a hot air station to remove old caps with — a few years ago I bought a generic Chinese one off eBay for $40 including shipping. If you search "828D" you should get a few listings. Not sure how much they're going for now, but mine has held up well over the years and been very helpful for SMD work. I've done three Mac logic boards with it and am preparing to do a fourth. Probably doesn't compare to a $1k+ model, but it has been more than adequate for my vintage Mac projects.
  4. Well guys, after a little back and forth with the seller, I got a refund for the CC and he told me he is glad I can at least use it for spare parts. Really nice guy, I feel a little bad. But I digress, I have some CC parts in the mail and should have a complete functioning system soon. Start in the logical place... Our first stop is the CC logic board. It's working, but probably won't be for long—it's very dirty and covered in cap goo: So let's assemble our tools and get to work: Caps removed, solder pads cleaned: For this board, I'm going to go with a cleaning agent I haven't experimented with before: ammonia. It's supposed to neutralize acids, so I'm hoping a good long soak will neutralize the corrosive cap goo. Here, I have diluted it with hot distilled water: The reason I didn't go with full submersion is that I don't want to lose the manufacturing stampings ("QA NAI" and "ICT") on the board. The last board I recapped was my SE/30, and the isopropyl alcohol I used then took a few markings clean off the board. For this CC board, I am submerging into the ammonia bath in parts: After a few partial soaks, I let the entire board soak in distilled water and then did a careful scrubbing and oven dry. Here is the board completely cleaned and ready for new caps: And here it is with some new polymer caps and a fresh Tadiran: I am very pleased with how this recap turned out! This is my first time using polymer caps, and I absolutely love the finished look. It's very close to original, but these new polymers will never leak again. I put the board back into the broken CC and it appears to have survived the surgery quite well. It booted right up and all ports are functional. I now have a pristine original CC motherboard! There are more goodies in the mail and they should be arriving sometime this week. Stay tuned... Edit: not sure why, but the forum software insists on adding this picture back in at the end each time I save the post —
  5. You read my mind Jinnai; once I slept on it I realized it might be more fair if I asked for a partial refund. There are quite a few usable parts here; notably a working original CC logic board and an analog board that looks to be in great condition. But then I checked my email and saw that the seller issued a full refund without asking for the machine back. Ah well. I've got leads on another CC, and I'll be going ahead and refurbing the parts I'm going to keep from this broken one. More to come in the following week or so!
  6. There is also a break by the floppy drive and in the top left corner of the display, and the rear bucket has chipped corners all around. The case has a strong mildew smell to it and I've also found the CRT was damaged once I plugged the machine in for bootup: That dark spot is much more noticeable in person, and I've determined it's not because it needs degaussing. This is really only usable as a parts machine. I've requested a full refund—hopefully the seller is cooperative.
  7. Disaster strikes! Honestly one of the worst packing jobs I've ever had on a vintage machine. I had a bad feeling about it as soon as I saw how small and tattered the box was.
  8. "Let me take ya'll back man, as I do so well..." Back in 2013, I was bitten by an overwhelming wave of nostalgia for 90s Macintosh. Not any model in particular, just 90s Macintosh as an entity. Beige plastic; the Chicago typeface; whirring hard drives and errant "eep!" sounds accompanied by rigid error messages. The phosphorescent (and somewhat blurry) glow of tube monitors. The musky, sweet smell of old ABS plastic housing toasty circuitry. You know what I'm talking about. You wouldn't be on this forum if you didn't. I was in my early twenties at the time, living in my parent's garage as I deliberated what the next step should be. I had just dropped out of school and I was waiting tables. Totally lost. I needed a safe space to rest from the overwhelming confusion of life, and the warm confines of System 7 beckoned to me like a cup of coffee on a rainy day. I tried to resist, but (if I remember correctly) after a long night of drinking I went on eBay and commissioned this work of art: Rest in pieces, old friend. You were too good for this world anyway... It was my first vintage Mac, and its limitations made it difficult to appreciate the first time around. It (obviously) had no CD-ROM drive, and although I got a network card for it, I wasn't able to figure out how to FTP data to System 7. The motherboard had leaky capacitors that I wasn't equipped to deal with, and I didn't own anything else with a floppy drive at the time. I played for a bit with the software that came loaded on the hard drive, but after about a year, I felt that I had exhausted all possibilities. I put it back in its shipping box and off to its next owner it went. I didn't think about it too much. Life went on, as it tends to do. I moved out of my parent's house. I restored the Color Classic's funky sibling, LC5xx. I left Southern California for the Sacramento region. I even disavowed Color Classic for a while: Me three years ago, thinking Color Classic and I were better off as friends... I finished a degree. I moved again, this time to downtown Sacramento proper. I started a career. I got my own place. And it was then that old memories of Color Classic began to resurface. "That was a pretty sweet little computer. I kind of miss it." The memories felt warmer than I remembered. I started watching YouTube videos about Color Classic. There are quite a few on there these days! Back in 2013, there was very little about the machine on YouTube. I started looking at my writing nook and thinking, with more and more longing each time around, that a Color Classic would be a wonderful addition. While it'll never be the hardcore barebones writing workhorse that my SE/30 is, Color Classic has a strong emotional pull on me, and there's something to be said for that when looking for the ultimate writing tool. The more I thought about it, the more I realized I want a Color Classic again. And the more I thought about that, the more I realized that my taste and approach to vintage computing has evolved a lot since 2014. The limitations of Color Classic aren't really a problem for me anymore. I've gotten a few DOS/Windows 95 computers, and I've found DOS gaming (with crunchy AdLib/FM synthesis as the soundtrack... yum) to be so much more fulfilling than Mac gaming. I don't really care that Color Classic can't game well anymore. I mostly turn to my vintage Macs as writing machines, and as a comforting presence that connects me with childhood. The lack of CD-ROM is no longer an issue, either. Not only do I now own an external Apple SCSI unit; I also have external SCSI2SD and have become much more proficient with networking and FTP. I also have several USB floppy drives for my modern computers, and have become expert at using "dd" in modern MacOS to write floppy images. So I started browsing eBay for Color Classics again... Stay tuned!

    Just curious, why do you prefer to keep the original drives running over other solutions?

    Out of curiosity, does anybody know where to measure and how to adjust B+ on these boards?
  11. Hi all, we've had threads about "which compact is the best?" before, but I'm wondering if we can have a thread specifically about the vintage Mac that needs no introduction: the SE/30. It gets a lot of love, and seems to be most appealing and valuable out of all the compacts. People want this thing. But why? What makes it such a desirable model, and, more importantly, does it live up to the hype? -------------------------------- I own an SE/30, and personally, I have found it to be a fantastic little computer that presents enormous tinkering possibilities. Doing a full restore on an SE/30 is just the beginning of the road; once you've it running nice and stable, the upgrade possibilities are endless. And that, I believe, is what makes it such an alluring little machine. It's relatively powerful to begin with, and can only grow stronger the longer you own it. That being said, the SE/30 is my first compact. The other compacts may be equally or even more charming. A lot of what I love about it—the sharp little black and white screen, classic MacOS vibes, the way it's small enough to sit unobtrusively on the corner of your desk—also applies to the rest of the compact line. So am I in love with the SE/30, or with compact macs in general? Curious to hear from those who have had lots of compacts for a hopefully objective conversation.

    Macintosh LC very quiet speaker

    I had very faint sound on my SE/30 when I first bought it. New caps brought it back to regular volume.

    Have you popped the chips all the way out of the sockets (carefully, so as to not bend the pins) and then put them back in? Often, they need more than a push.
  14. Did someone say R G B ?! Sounds like this is going to be a very refined product when it's done. Looking good so far!
  15. If you put the SD card in a modern Mac, it can read the files on it no problem. Can't write to it though. If anybody knows of a program to make an actual image of SCSI2SD SD cards, I have actually been curious about that lately myself!
