hi guys,
got a 486 with amd 100mhz.. the board is Suk Jung SJ-DG486/3VLS https://theretroweb.com/motherboards/s/suk-ju … g-sj-dg486-3vls

as the title says im trying to work out where the data and clock pins run to..

im having problems detecting the keyboard and it is no doubt due to battery leakage damaging the tracks..
i have removed the original battery and hooked up the external battery..
board fires up but halts at keyboard not found..

ive tested the 5v and ground pins, they have continuity to the power conectors (P8 P9).. and i am also getting the keyboard lights coming on..

i figure it is the data and/or clock pins/ tracks have issues..

i cannot work out where the clock and data pins run to?
ive googled and most results say they go the keyboard controller and im assuming and/or bios chip?..

i see there is definite track damage around the area that had the battery leakage..

can anyone point me to where they think the data and clock pins run.. and where the keyboard controller chip is..

cheers guys
