    I need a new battery.

    No, When I say 4000 mah, it's two 3.7v batteries in series for running but split up for charging. One 5v regulator but two charging ICs.

    I need a new battery.

    Actually I have a design that can be used on the black and white models. I'm just very busy right now and can't mass produce them, but I'll sell you my one and only prototype. I can also release the files at some point, but I'm very busy right now so I will not be producing more at this very...

    Classic with battery damage—can it be saved?

    Classic boards are the only ones I've been able to save after a battery leak. It's best to clean the corrosion, remove parts in the area and check traces.

    Maybe someone could adapt a Pistorm: https://amigastore.eu/853-pistorm.html

    Reverse Engineer the PowerKey by Sophisticated Circuits?

    If one just wanted to control plugs via the power key(without any software) on an ADB keyboard the process would be fairly simple. Because the ADB keyboard grounds the power pin whenever the button is pressed you could just use a set of relays in a holding circuit like this (but with ground and...

    Lithium Polymer battery for PB100 (and maybe portable)

    Yeah I guess, Basically you can't fully charge your batteries together with a 7.5v charger, you need at least 9 volts to charge a 2-cell lithium battery. In charge mode, my circuit splits the batteries so the can be charged individually, but doing this has the downside of the batteries not being...

    Lithium Polymer battery for PB100 (and maybe portable)

    Yes, it is. In fact I'm working on a pb140-180c battery pack using the same circuit.

    HDI-20 to IDC-20 adapter for use with Floppy Emu

    Yeah, could be a faulty swim or cap goo in that area?

    HDI-20 to IDC-20 adapter for use with Floppy Emu

    I've done the exact same thing and have not had a problem, is it possible you swapped a pin or something?

    Need help designing a PCB/Recreating one.

    I told home that basically one will have to be disassembled, then I can make a schematic and then a pcb.

    Lithium Polymer battery for PB100 (and maybe portable)

    Yeah probably, nothing is stopping you from buying the parts and building this circuit.

    Lithium Polymer battery for PB100 (and maybe portable)

    Circuit may work but the form factor is not the same.

    Diagnosing Macintosh Classic II not booting

    The board needs a wash and new caps.

    Mac Classic fuse blown after TDA4605 IRFBC40 replacement

    I see, It might be worth to check the rectifier(KBL08) and make sure it's okay: https://www.parduebrothers.com/siliconbridgerectifiertesting.pdf Also check the capacitors on the left side of the rectifier.
