    Newly recapped Powerbook 160, screen artifacts or typical passive matrix?

    After swapping out the 11 caps on the screen with tantalum equivalents, and the 2 on the inverted board with electrolytic/polymer replacements, the screen on my newly acquired PB 160 has come back to life! Huzzah! It does however still exhibit quite a bit of smearing/shadowing/ghosting (not...

    Cleaning trackball assembly

    Just starting to get to work on a new PowerBook 160 project. The whole trackball roller assembly is understandably a bit crusty (though it could be much worse). Any reason NOT to submerge the whole black roller assembly into IPA to help loosen up the gunk before I go at it with a soft brush? I...

    Anything to be gleaned from this PB160 photo?

    Hi all. I am considering picking up this PB160 from a local seller as a restoration project. I’m a computer engineer with several vintage 68k restorations under my belt now and I’ve read all about what to expect with this model, so I’m not concerned about the restoration itself. I’m only...

    Coolest 68k Powerbooks to own?

    Hi all. I’ve only collected and repaired 68k compact Macs thus far, but I’m interested in adding at least one Powerbook to the collection. In your opinions what are the coolest 68k Powerbook models? Fwiw I found the below thread that has some great info regarding various models’ repairability...

    Framework for developing a 68k application w/ serial port communication

    I'm contemplating a small project that would allow me to send/receive serial communication between my SE/30 and an external microcontroller unit (via the serial/modem port). I've written a dozen or so embedded C++ apps in the past that include custom MCU to MCU serial communication protocols...

    Best way to test serial ports on an SE/30

    After several rounds of troubleshooting I have my external floppy and SCSI ports fully functional again. Now it’s time to focus on the serial ports. What are the preferred ways of thoroughly testing these on an SE/30? Is it possible to cable them together and test them in a loopback...

    Mac SE/30 ripple artifact on right side of screen

    After recapping the logic board on my SE/30 my video output is working again, but I’m noticing an intermittent ripple effect on the right side of the screen (video link below). It seems more prevelant during boot up (especially a cold boot), but I have noticed it occasionally later on as well...

    Mac SE30 Expansion Bracket Screws

    Does anyone happen to know the official screw size for the three sheet metal screws that attach the rear expansion bracket to the frame? The unit I’m working on came with the bracket unattached and no screws. I’ve tried several sizes I have laying around, but nothing I have fits perfectly. Thanks!

    Backwards progress with SE/30

    Hello all. Longtime lurker, first time poster. It has been while since I owned a compact Mac, but recently came across an SE/30 for sale that was in surprisingly good shape. The seller insisted on booting it several times to show me it worked, and it seemed to boot fine to the internal SCSI...
