  • apple iic ram upgrade question

    From Logan T@21:1/5 to All on Sat Feb 25 20:51:26 2023
    hello i just became the new owner of a iic and have been restoring it to my best knowledge and skill. i completed working on the keyboard and was next looking at various boards trying to identify issues. this computer came with a applied engineering z
    ram ultra 3 upgrade which is nice. i noticed that there is a large 3.6v 100mah battery soldered onto the board. the battery is labled, varta mempac. anyway there is brown guck oozed around the battery that im guessing is battery acid. the question is
    can i remove the battery as im guessing it is just for some memory preservation or something. maybe someone could link a replacement battery or a hack around solution thanks.

    Eek! Get that sucker outta there!

    I think that board includes a real-time clock, and the battery is to
    keep it alive (though it might also allow you to keep a RAMdisk alive).
    If you snip it out, you just won't have time (or RAMdisk) past a power
    down, 'till you replace it.

    ok i have it removed, there is plenty of corrosion on the board from the battery hopefully it will be ok
