I found this Octek motherboard on a scrap yard for 10$, and just from first glance I can tell it has got such problems:
1) All the socketed ICs are removed,
2) One resistor is ripped off,
3) 6 Chipset pins are shortened,
Getting a keyboard controller, both BIOS EEPROMs and 146818P CMOS won't be hard, but I have problem when it comes to U35, U11 and U17 sockets
They are labelled as ' 16L8A' and '16L8B', so judging from parts numbers and pics of that motherboard, but of different revision I think that these sockets ought to be populated with PAL chips.
And here comes my question, since I have no experience when it comes to that. Do I have to program these chips with microcode, or just order such chips and socket them?
I think that the biggest problem are these shortened pins, also as You can see, there is a ripped of resistor near that SMD chip ( labelled as R25).
Do anyone of You have a knowledge what should be it's resistance?
Thanks for any help
