I know some people looking for rtc chips, sound chips, apple custom chips for battery bombed boards, or cap damaged chips etc. i was going over some dead powerbook 100 series boards and noticed that sound chip is same as lc series computers, well lc and lc ii for sure. They also have rtc chip that works on classic mac, iici, q800, q650, centris 650 boards, maybe more? Not sure if there is a data base of cross reference chips. Hope this helps someone looking.
