    Wow. Now THAT is a project! Interestingly, your board layout looks a bit different than mine: https://www.icloud.com/sharedalbum/#B1lG4VTwGGUEiDp Curious if there was more than one Rocket design, or if your design looks different simply to accommodate different chips.

    I Bought 8 x 16MB SIMMs from tindie.

    You said you have a ROM-inator II ROM SIMM and I can tell you for a fact that is likely your trouble because the PCB is very thin. That remains true even if you had no issues prior to installing your new RAM. Even with ROM Clips, you may have trouble. I had my stock ROM SIMM slot removed and...

    Apple IIc TEARDOWN & MacEffects Clear Case REVIEW [VIDEO]

    Making this video was a learning experience. Despite asking many people for advice and watching YouTube videos on the subject, I still had trouble with the Speaker install, but ultimately I got it locked-in with hot glue. I love using IIc Drop-to-Open technique that Javier Rivera taught me...

    SuperDrive (floppy) maintenance

    There is yet another case that I posted on FaceBook yesterday, and have been speaking to @fehervaria and others about. My case pertains to bad 1.44MB SuperDrive heads. That problem has nothing to do with Zero Track or Motor misalignment. In my case, I know that to be true because I removed the...

    Vertical band on screen

    Was the problem ever resolved? If it was, what was the root problem? Also, many people have asked me about that model 157-026C flyback over the years, wondering if it is compatible. I've never tried it myself. So because you bought one and installed it, I'm quite curious if it works as...

    Netatalk 4.0 - Future-proofing Apple File Sharing

    Thank you. That is the kind of concise info I was suggesting be added for clarity. "Why build from the source? So you can enable AppleTalk, which isn't enabled in pre-built packages." If it is not added, it's perfectly fine. I am just making a suggestion for newbies like myself who tend...

    Floppy Failure Help

    Here's the moldy floppy I mentioned in my previous post, which negatively affected my heads, even though I had just cleaned the heads and the entire drive only hours prior to testing that disk.

    SE/30 Y3 Crystal Replacement Recommendation?

    @ComputerCompulsive & @naruse When you've had opportunity to test the drop-in replacement recommended by @Bolle and/or try the other information provided in this thread, please be sure to let us know if your Y3 crystal issue was resolved and what specially resolved it. Thanks!

    Netatalk 4.0 - Future-proofing Apple File Sharing

    Much clearer. An excellent textual improvement, to be sure. Great job! Please note the spelling error here: Should be spelled: specification (Not trying to be overly critical but instead helpful, pointing out the obvious.) My new suggestion pertains to helping newbies understand the...

    Floppy Failure Help

    Do any of those disks make a louder than normal sound when you insert them and they start spinning? If so, look at them under a lens or microscope to see if there’s any mold or debris on the disk itself. To do that, you need to slide the metal slider open so you can see the disk itself. The...

    SE/30 Y3 Crystal Replacement Recommendation?

    But now that I ponder it further, it very well could be ESR that's the problem here, rather than Load Capacitance. You see, those cylindrical CAN oscillators are typically used in clocks and watches, and in those applications the XTAL ESR is very high, on order of 50kΩ, 90kΩ or higher. But if...

    SE/30 Y3 Crystal Replacement Recommendation?

    Examining my stock SE/30 motherboard and the BOMARC schematic, I see this... Looking at Bolle's Github Gerber files (via JLCPCB website viewer), I see on the top side of the board, he has designed it to accept either the old cylinder-shaped crystal (shown above) or the kind more commonly used...

    SE/30 Y3 Crystal Replacement Recommendation?

    I realize you aren't doing an SE/30 Reloaded build, but sometimes those builds have BOMs with a modern parts list you can buy today. The SE Reloaded build's BOM is like that. Even so, I've never done an SE/30 Reloaded build myself and therefore have no experience selecting parts such as the Y3...

    Another way to clean isopropyl alcohol used for cleaning resin 3D prints

    True, but I often put a variety of drive parts in 100% IPA and clean then with a toothbrush, one-by-one. And if a new, replacement part is dirty, I may throw it in too. Cleaning everything I dunk in IPA takes time, and by the time I get to some of the parts, they may have been soaking in the...

    Another way to clean isopropyl alcohol used for cleaning resin 3D prints

    Oh my. I don't even drink alcohol but that knowledge almost makes me want to give it a try! 😆 (I'm a Steve Jobsian "not fond of rules" rebel at heart.) Bruce, pardon my utter ignorance about resin printing and IPA, but if I have a floppy drive gear made of resin which is a bit dirty or may...
