    Duo type 3 battery

    after some research on old 68k threads and the interwebs in general it seems the general consensus is that 2/3A and 4/5A cells are the correct ones for the type 3s, the 2/3s are slightly shorter and provide more room to work with, However I am still unsure of where to buy said cells

    PowerBook Duo 280c no chime

    as others have said it is most likely caps, I would suggest replacing the ones near the DC jack first and verifling that the problem is solved before tearing the display assembly open and attempting to recap

    Best MacOS for 2300c

    Yes I was talking about writing installation disks, good to know it should work on my mac. I’m leaning towards 7.6 considering the 8 meg card installed

    Best MacOS for 2300c

    Unfortunately I only have a new MacBookPro so it I’m only able to run newer versions of OS X. I have a Windows 10 PC, would that work as well?

    Best MacOS for 2300c

    I have an 8 meg card in it so along with the motherboard RAM It would be 16 megs?. I’ll be hopefully finding a larger ram card soon

    Best MacOS for 2300c

    I think I’ll go with 8.1, can I use a modern mac with a USB floppy drive (Intel) to download the files?

    Best MacOS for 2300c

    As I recently got a 2300c with no hard disk i immediately purchased an IDE to CF adapter and I am now wondering which version is  optimal to run on this machine

    Airport cards that support WPA2?

    Are AirPort cards PCMCIA?, I just looked at one I had laying around and realized they have the same connector. Does this mean the AirPort slot could accept a PCMCIA card?

    DuoDock Nubus card compatibility

    Definitely, when I used to have a dock I replaced a few of the smaller electrolytic capacitors and the RIFA cap, When I get one soon It will be at the top of my list to do again. As much as I like putting a modern and stable power supply in I absolutely hate hacking the casing to fit it, I love...

    SSD in Duo 280c?

    Yep!. The 2300c had two different connectors, one SCSI one IDE, however they use different interconnect flex cables so check which one you have first.

    DuoDock Nubus card compatibility

    Ah I see, Like you said I doubt the Dock would even be able to supply enough power for the rocket, it would most likely be unstable under load

    What would Disk 1 do?

    DuoDock Nubus card compatibility

    I'm guessing the second NuBus slot could be used as an exhaust?

    DuoDock Nubus card compatibility

    I'm sure it wouldn't be hard to fit a fan, plus as long as it's not being used for long periods of time hate should not be a big concern
