  1. Try opening up Keychain Access (Application Folder > Utilities Folder), Trash the key pertaining to your Airport password in the System Keychain, then reconnect to your Airport, it'll prompt for the password, then type it in. Voila! Sounds like also the PRAM battery is getting old or low. You may want to see about replacing it, if possible. 73s de Phreakout.

    Pro tip for recapping boards

    I can confirm that this does work, after recapping 2 SE/30 boards. I would probably go so far as to say it may be far more safe, compared to using the dual pencil soldering iron method. No pads are ripped, didn't see any liquid leakage, though. One note, when cutting, if you can't get the tool to cut on the indent of the cap, you can safely cut a bit above that. Looking inside the cut cap, I see 2 rubber discs (possibly seals) and there appears to be a mostly solid substance used as the electrolyte. Not sure what the chemical or substance is. Other than that, it is the most clean and pain free method I've tried so far. YMMV. Further study required, please. 73s de Phreakout.
  3. That's great, Uni! And even rare, a significant other who shows interest! This can even open doors for both of you to careers in repairing electronics, as well. My dad, a licensed electrician for over 40 years, taught me how to solder when I was about 8 years old. I later took electronics courses at a vocational campus, while still in high school, and that allowed me to gain further experience up to Series/Parallel Resonance circuits (the basics of how radio and TV tuner circuits work, how to diagnose and how to repair). I was trying to advance further into digital logic and control circuits 11 years ago, but I ran out of funding to continue taking classes; that, and life got in the way. Oh well. 73s de Phreakout.

    Strange SE/30 Goings On

    Is that a Zip 100 or a Zip 100 Plus? If the first, I would check to see if termination is enabled. If the latter, the 100 Plus should enable termination automatically. Next, make sure that the Zip and EN/SC adapter have different SCSI ID numbers. Finally, try turning both external devices on first, then power on your Mac. It should boot normal from there. 73s de Phreakout.

    Strange SE/30 Goings On

    Correction: System 7.1 through Mac OS 7.6 Compatibility With Macintosh Computers. The SE/30 DOES NOT utilize system enablers, no matter what version of System 7 you run. Try downloading the System 7 Tune-Up version 1.1.1 from the Old Apple software downloads page: Here, and this is the "Readme" file, concerning the Tune-up. 73s de Phreakout.

    Strange SE/30 Goings On

    Correct me if I'm wrong, but didn't some of the early versions of System 7 have issues with disappearing or missing folders and icons? And wasn't there an extension or enabler issued to fix that problem? 73s de Phreakout.

    ZipMacPLUSā„¢

    Alot, but Trash, can you start posting in "I-Can-Haz-Cheezburger" speak? It makes for a more interesting and entertaining on your posts, imho. 73s de Phreakout.

    Capacitor Replacement Thread . . .

    Fyi, I am trying the cap-clipping technique and so far it's not that bad. My hats off to using this method, but please use your best judgement. Not all boards are made equal; there can be hidden severe damages due to age and/or corrosion. So far, one board is coming through with flying colors. 73s de Phreakout.

    Pismo G3 - won't return from sleep mode in 9.2.1/2

    In addition, can you boot it into Open Firmware mode and tell me what version of ROM is running? IIRC, the last firmware update put it to version 4.1.8f5. I think that version may fix the sleep issues; reading the descriptions tells me the update improves overall stability and performance issues. Whilst in there, try also typing in the following incantations (minus quotes): reset-nvram [Return] set-defaults {Return] reset-all [Return] If the firmware is not up to 4.1.8f5, do a search for the update on Apple's support pages, reboot into OS 9 and install the update. To recall, Apple shut off software updates for anything earlier than OS X Tiger, so a manual search and install would be in order. 73s de Phreakout.

    ZIP100 Plus!

    If you do in fact have a Zip 100 Plus external drive. it means that it will accept both SCSI and Parallel printer port as a means of connecting to a computer. One port is for SCSI, the other is for the parallel printer port on older DOS/Windows PCs. So far, it appears that it may have automatic SCSI termination or the termination is enabled by factory default. After doing some research on the Apple Discussions forum on Apple's website, someone posted having the same type of drive and mentioned it being "self-terminated". So that means it has termination enabled as a factory default. My advice if you have additional external SCSI devices to daisy-chain together, make sure the Zip drive is the last one on the chain. It shouldn't matter which SCSI ID number (5 or 6) that you chose, as long as you don't assign that same number to another SCSI device on that chain. 73s de Phreakout.

    SCSI and termination.

    Your welcome. I guess that's why IDE replaced SCSI as a standard for hard drives. Technically, they both are so alike. But who wants to monkey around with confusing DIP switches and settings for these kind of drives? 73s de Phreakout.

    SCSI and termination.

    markyb86, The reason why there are terminators on SCSI is due to the fact that there is such a strong signal sent down the wire. When it reaches the other end, if nothing is there, it will bounce the signal back to the source (it echoes). It's almost like how echoes reflect off of the sides of mountains. Without a terminator, you will experience a variety of symptoms from "ghosting" (the icon for that SCSI drive appearing and disappearing repeatedly), "mirroring" (the icon shows up twice, one below the other) or no device at all. The terminator acts like a shock absorber for the entire chain. One thing to remember about SCSI is that you can "daisy-chain" devices together: Mac's SCSI port<===>SCSI device<===>SCSI device<===>SCSI device<===>etc. This is why there are at least 2 SCSI ports on a SCSI device. SCSI, offers up to a handful of devices you can link together. But also in order for a successful set up, you must have assigned one SCSI ID number per device. Here's how it breaks down: SCSI ID #0: Reserved for the Mac's first internal hard drive SCSI ID #1: SCSI ID #2: SCSI ID #3: Generally reserved for internal and external CD drives SCSI ID #4: SCSI ID #5: SCSI ID #6: SCSI ID #7: Reserved internally for the Mac (not allowed to use) Regarding SCSI, according to tech writers David Pogue and Joseph Schorr, there are "The 3 Rules of SCSI": 1.) Termination: Typically, the Mac's internal hard drive will have its terminator enabled by default. Externally, regardless of what the SCSI device is, you must have a terminator installed on the last device on the chain. Now, some external SCSI devices may already have termination installed and (depending on the manufacturer) there may be a switch you can adjust to turn the terminator on or off. Also, some SCSI devices may have "active termination" built-in, where a circuit will turn on or off termination automatically as needed. 2.) SCSI addressing or ID number: Each SCSI device must be assigned their own number and you can't share that ID number with another SCSI device. The physical order of devices can be independent of their ID numbers and the last device on the chain doesn't have to be the highest or lowest number assigned. However, Apple recommends you give higher numbers to the devices you use most frequently and lower numbers to devices used less frequently. 3.) Cabling: Keep the cables as short as possible. You're allowed up to 18 feet (6 metres) total, but you must subtract from that figure the amount of cable inside an external device. Finally, the quality of the cables make a huge difference in the successful maintaining of SCSI. So if you can, buy cables from a name brand you can trust. 73s de Phreakout.

    Capacitor Replacement Thread . . .

    Amen to that. In a pinch, those caps will work. Don't know if they're any better than SMD orange colored tantalums I use (the same ones that trag uses). You'll just need to make sure you trim the leads short enough and make sure you install them in the right position: + to +, - to -. Duh. 73s de Phreakout.

    Capacitor Replacement Thread . . .

    I agree. Although, I am finding that it may be better to try cutting the old caps off, like what Mk.558 has posted. I agree as well. But to be more gentle on the board, use a small wire brush kit like this. Not saying to get that exact kit, but one similar to it. That one I posted is uber weak; no stiff strands of wire in that brush, compared to the previous model kit they carried. Also doesn't hurt to use a pencil eraser as well. 73s de Phreakout.
