    John's SE #1 Rebuild

    Well folks, time for another rebuild thread. Purchased this fine SE in that huge lot I posted about. Absolutely disgusting. Covered in spider webs, grime, sticker residue, major burn in, dead bugs inside, dusty, stains, yellowed, etc. It's an SE 800k 1MB 20SC... Originally. Upgraded to a 160 MB quantum drive (still works great suprisingly! Was it the quantums that are good quality?) And 4MB ram! No maxell bomb in this one. Swapped out the battery. Did a smoke test. Bonged. Nothing on the screen. Then, suddenly, the whole thing was gray. Stayed that ways for a minute. Of course, now I know since it has lots of ram, that was the memory test. Whoever had it last adjusted the desktop to take up the entire screen. Got to order some tools to adjust it back now... Looks like a medium to high hour unit. Floppy drive inject won't work so couldn't test it (hmmm... Wonder who will have spares... Oh, that's right. ). First of the SE restore series I'll be doing with all of my new SEs. Some before photos... (Case not fully installed . Removed and checked some stuff and didn't bother screwing it back on)
  2. I would highly recommend getting all three boards recapped. Analog, PSU, and logic. Then you'll be set for decades. Let it sit turned off and unplugged for an hour, and then discharge it. It should have a bleeder installed. You might see a spark but probably not. After that, remove the cap and you can continue on taking it apart. Make sure to lube the floppy drive while it's out, and you should probably replace the eject gear.

    PowerBook 180 hard drive died today

    I have a couple of dead Connors and a working Quantum Go Drive, but I'd like to sell them with at least one of my parts powerbooks. An SCSI2SD is a much better choice. I have one in my 140. Fast. I made a 3d printed bracket too.

    Free Macintosh Plus!

    No Jinnai, you're correct. Well, really the cap is there because without it the anode wire itself would be arcing everywhere. You NEED the cap to stay "glued" down. That's what the red you usually see in that area is. Glue. You also don't want any nicks damaging the cap. So it sounds like you should reglue the cap somehow. Or, like one of my junk SEs had, duck tape it.

    CURRENT most reliable Powerbook?

    I know I have an ungodly amount of threads here... Sorry... I am wondering what the most reliable Powerbooks are as of now? I mean stuff like least screen issues, no to little tunnel vision, cap issues, plastics, easily expandable, etc, EXCLUDING the 3xxx, 5xxx, 14xx. I mean 1xx and 5xx series (68k). I will be looking for a new Powerbook soon and want to get a no nonsense one that wont have many issues.

    Desk lamp too close is my guess.

    PowerBook 165 Grid Effect on LCD

    Looks like you used a bunch of solder on those caps. You sure the blobs of solder aren't touching other traces or ics? I can't really tell from the photos.

    PowerBook 165 Grid Effect on LCD

    Yup, that happened to be a speck of solder shorting out a trace. It appears to be in the top section, so check around the top section of the PCB for that. Should be close to where the pads are.
  10. You can look on eBay, but expect to pay at least $100 for one.

    Advice on repairing Mac IIx

    Replace caps first. Thats at least the cause of your power issues.
  12. Got a few things recapped by a member here. Everything was well packed. Got an SE/30 PSU with a smashed in power switch, broken 160 LCD, and a working inverter back today (Courtesy of USPS). Whats going on with this LCD? Is this a cap related issue or is this damaged from USPS? Three of the four corners were chipped and cracked but tested fine and this does not appear to be an issue related to that. What is so bad between me and getting powerbook screens recapped? Gonna have to try doing this myself next time. Appears to be something up for sure with that bottom ribbon cable, but it does not appear to be "bad". Mouse cursor moves fine, menus pop up. Any windows are drawn weirdly and extend off the screen. Screen "shimmers" or jitters. Tapping or shaking does nothing. I have reseated LCD cable and logic board cable a few times. Sound works and desktop appears which tells me this is a screen issue.

    Need some quick opinions on this 160 LCD.

    It is the IC itself, so I am going to skip trying to repair it. Its for sale with a bunch of other Powerbook stuff. Thanks Techknight for chiming it.

    Diagnosing the 9600 From Hell(tm)

    Yup. If theres continuity then it can be ignored.

    Diagnosing the 9600 From Hell(tm)

    Just get a multimeter and test for continuity. That will tell you right away.

    Portable and 12 volts !!!

    Keep it and talk with the all knowing Portable wizard. Techknight.
  17. I personally would sell the whole thing as a parts/repair machine. Dont separate anything. That ways you are not liable if a part doesnt work.

    How interesting is the Lisa?

    I see the Lisa in the category of a 128k. It's pretty much useless today, underpowered, etc, but would I want one? Yes. Do I want to spend over $500 for one? No. It's not like a IIfx, which is uncommon and expensive, but super useful.
  19. Hi all, My Powerbook 140 clicks randomly, but has an SCSI2SD, good screen, etc. I bought a 145 off ebay. It was to my knowledge that 140s, 145s, and 170s have the same logic board, but CPU boards are different. I first tried swapping the entire bottom but installing my SCSI2SD. I did this, plugged in the main cable, installed the bottom, and plugged in a power adapter. It started chirping loudly. I then noticed it was my unrecapped adapter. No big deal, it just needs the caps replaced. I swapped it with my KNOWN GOOD recapped adapter. Same thing, chirps loudly. Next, I opened it back up again and removed the CPU card from the 145 and installed it in my 140 bottom, and installed it with my 140 top (Keep in mind all 140 stuff is known good). Plugged it in. Chirped once quietly (Like it should), and turned it on. It chimed, lit up the screen. Yay! Then all h$#% broke loose. The speaker started buzzing super loudly and the screen had gibberish and lines all over it. I quickly unplugged it. What the heck is going on here? Am I wrong, 145s are not compatible at all with 140s? Or is my 145 completely dead? I dont want to try anything else until I find out whats going on. Bad 145 CPU board? I know the 145 logic board is junk, it makes the adapter chirp when plugged in and not even on, so not even gonna attempt to use it. Got a modem card and RAM card out of the probably dead 145 though.

    NEED HELP with a Powerbook 140 to 145 upgrade

    Tested finally. The supposed 145 board: The stock 140 board: Maybe the 145 board is really just an old 140 someone threw in. It says copyright 1991 and 140/170.

    NEED HELP with a Powerbook 140 to 145 upgrade

    Ah, that makes sense. What is weird is that the CPU board is labeled 140/170... I will try and run a test when possible. That would be great if it could keep the 140 name and run at a 145 speed.

    TiBook - bottom casing coming off

    I would use JB Weld brand clear epoxy. I have had bad experiences with JB Weld never fully curing. Epoxy is idiot proof and just works. And it's faster curing. Used it on my Powerbook hinges which are holding up fine.

    Is my flyback transformer dead?

    Use alcohol or similar to clean grease, use white lithium to lube. Put a dab on the motor rails and such too.

    NEED HELP with a Powerbook 140 to 145 upgrade

    Just tried the SCSI2SD again to confirm. Works great now... Perhaps there was a bad connection somewhere and replugging everything helped. I'll update this thread with the results of my 140->145 upgrade. Errr... Isn't a 145 CPU like... Supposed to make it a 145 or are there extra things on a 145 logic board that makes it a 145? Still says it's a 140. Well ... In all I got a 2mb ram card and a modem. And I have narrowed it down to the logic board. Anyone got a 140/145/170 logic board that WORKS laying around somewhere?
