The monitor weighs more.
Patater wrote:. . . (well, more because I am curious about this), I would like to show you all something interesting I found inside the LC III. The LC III logic board has a few green wires connecting the chips U32, U22, and U7. I don't know what any of those chips are or how I could look them up (aside from just searching for numbers printed on them, which didn't get me anywhere). The wires were laid nicely and held in place with tiny beads of hot glue. The soldering quality isn't all that great though.
So, from this green wire find, I have two questions. First, do we have a good logic board reference we can use to find out what different parts are? Something like a BOM for various Macintosh models would be nice. And finally, what do you think those green wires are doing?

Trash80toHP_Mini wrote:I'd examine that board VERY closely for any verbiage, dates and revision#s you can find. With that much rework, you may have, either a very early production board or maybe even a prototype MoBo on your hands.
