    1.4mb floppy ejection

    One thing to also check is if the microswitches that detect the floppy type are working correctly.

    1.4mb floppy ejection

    I assume you also swapped the SWIM chip? You say you disassembled the drive. Could it be that you somehow altered the head alignment?

    1.4mb floppy ejection

    That can be because of a read error. Does that particular SE support 1.44M floppies (ie. is it an SE FDHD)?

    SE/30 ROM PCB replacement (820-0241-B)

    Did anybody ever make a replacement PCB for SE/30 ROMs? Mine soaked up a bit too much battery juice, but the chips themselves look fine.

    Is a Signature SE/30 case rare?

    I love having multiple rare SE/30’s then 😊

    Nearly torn cap on Mac SE/30, need advice

    There’s also the twist method, where you gently twist the offending capacitor side-to-side until it’s pins break due to metal fatigue. The advantage of doing it this way is that the glue underneath the solder pads stays cool during the cap removal, which keeps it strong. Afterwards the remainder...

    Performa 475 : Disk initialization failed because the disk is defective

    I’ve cleaned and re-greased the entire drive, and it now reliably detects every floppy I insert as 800k. Unfortunately, I’m only using 1.44M floppies. So next step is going to be to check the microswitches. Thank you for the hints! Will keep you updated.

    Performa 475 : Disk initialization failed because the disk is defective

    I did, using a Q-tip and some IPA; didn't change anything. The drive otherwise looks fine inside, nothing is obviously damaged. Should I be looking into the SWIM (if LC 475's even have a discrete SWIM...) instead?

    Performa 475 : Disk initialization failed because the disk is defective

    I'm having a similar issue with a stock LC 475, but in addition it also won't read formatted disks. The system otherwise functions fine (though I haven't recapped it yet, which it probably needs). @Amon_RA Did you ever figure out what the problem was?
