This could be chip-sockets.
BUT: PLEASE DONT USE CRAP LIKE ATARI DID!
GET SOME DECENT TURNED-PIN TYPES FROM SOMEONE LIKE AUGAT.
You may not get a second chance to replace them,atari pcb's lift there tracks easily.
also be carefull with the i.c.'s I have removed chips from sockets only to watch 1 pin fall-off!!!
this problem seems to afect chips from texas-instruments from 1977-early-80's.
good-luck. its a nice game!!!
