I have a Pole Postion video pcb that throws a RAM 27 error. I pulled the 9114 ram @ 7K, added a socket and replaced with a 2114 chip. The error is still there. I see pin #8 CE is pulsing and pin #10 R/W has activity. It looks like the LS7423 @ 6K and 7D are tied to this but they look the same as they do on my test board. I am a novice and looking for further ideas. Thanks!
