It looks like it might be worth a shot to redo the components, only a few of the pads were totally burned most still had copper after scraping at the pads. I have an LCII i can borrow all ICs from except for U29 (mc68hc70531dw). For the experts, is this one i can get from another common board? cant seem to find a similar chip in all the boards at my disposal.

See the naked gore of an exploded battery....
