    DuoDisk-][e compatibility...

    The DuoDisk can be used with a //c, but you only get the use of Drive 1. The //c doesn’t know what to do with the other drive.

    Add me into that mix as well. 😁

    SE/30 - Design for Drop in Replacement Power Supply

    @codevonlux Ahhhhh. Very interesting. When I looked at the PCB in the “Singapore” model, I didn’t see a Hitachi marking. I’ll need to go back and take a peek at that.

    SE/30 - Design for Drop in Replacement Power Supply

    @(o';'o) Heya Chris! Interesting that the Astec and 'Singapore' PSU's were the same. Their outsides differ, I guess the insides are close enough. I've attached photos of the power detail tags found on both the Astec and Sony CR-44 power supplies. Your amperage numbers are a bit higher than...

    SE/30 - Design for Drop in Replacement Power Supply

    @Juror22 I am glad to hear you're having a run of good luck with the two of yours. Unfortunately mine had a little bit more destruction due to the cap leakage that occurred. Mine came out of an SE/30 that had a good life and was well taken care of. Naturally, where one disaster strikes --...

    SE/30 - Design for Drop in Replacement Power Supply

    Hi Chris. I can certainly ship the PSU off to you, you pay for return shipping when you're done. If you're taking physical measurements...all good. I did test voltages and whatnot. It seems to be pretty stable if you need it for those details as well. Lemme know what you want to do and it...

    1.4mb floppy ejection

    While you have your drive disassembled, you may also consider a recap job. All of the floppy drives I’ve restored…all of them had at least 1 cap leak, some more. This was more evident in the external 800K drives rather than the internal ones. In the last external 800K drive I dealt with….the...

    SE/30 - Design for Drop in Replacement Power Supply

    Hi there. Yes, there is the one I call “The Made in Singapore” version. Worst of the lot. Their caps leak without fail…I have one that came out of an SE/30. Astec is a better grade of bad and I’d take one of those any day of the week over the Singapore version. Naturally, Sony is the choice...

    Another SE/30 rebuild with issues

    Hey there @MiMac. The items you seek are on Mouser. In the words of JDW... "NOTE: Product photo on Mouser is wrong but Description correctly says "4 Positions."" Female: 538-15-31-1046 Male: 538-19-09-1049

    Recapping Floppy Drives?

    @olePigeon Oh...I agree...an easy job to get done, to say the least. There are those major components that need lots more attention. I will say, that in the first 3-800k drives that I've recapped so far, all of them have suffered some form of cap leakage. The third one, was the worst yet...

    Recapping Floppy Drives?

    Interesting that I jumped into this thread when I did. The parts for recapping floppy drives arrived earlier today. Just tore down the first 800k drive...lo and behold, 3 of the 5 caps there...had leaked, albeit just a little bit. One even when I was removing it, the leg barely caught the...

    IIGS high speed scsi

    I must agree, adding a SCSI card to an Apple IIgs is a brilliant move...as is some extra RAM. Ended up purchasing two cards from GGLabs...an original Apple SCSI card...WAYYYYY too expensive now. One went into the IIgs with an Applied Ingenuity Inner Drive 20 [integrated power supply and hard...

    Recapping Floppy Drives?

    Well...on the subject of recapping floppy drives...if you're taking the time to recap a logic or analog board in a Compact Mac, it's a good idea to go over the floppy drive with a fine tooth comb. JDW put together a very in-depth and informative slice of videotape about how to recap a floppy...

    Recapping Floppy Drives?

    While looking around for videos about recapping floppy drives for the SE/30, saw this post. Albeit a bit late to the game, MacEffects sells a really fine replacement for the gears in the 800k and 1.44mb floppy drives that fail. While not the original, I have replaced the failed gear in 4...
