Okay,
having a ram issue with my Tapper, and I dont have a logic to test it yet... so I figured I would ask here and see if someone knew by sight which RAM chip (s) would be most likely to cause this issue.

I have confirmed it is a RAM issue by doing the self test and getting the slow blinking yellow LED.

Anyone know enough about this PCB set that they know just by the pictures which chip is the culprit?

Thanks!

PS Yes I know there is an X on my bezel...lol

With all the Tappers out there, nobody has had or fixed a similar issue?
 
I do not own a tapper PCB, but surfing around you can see PCB gurus saying that even if the self test reports a RAM error, it could not be the case: is the first RAM being declared bad? If yes, it could be some loose connector...

Are you sure you have not a monitor issue? Looks like the image folded to me...
 
Thanks guys!

No, not monitor... the monitor is only a 3 year old vision pro and works with other boards/games. So the monitor tests out.

I just borrowed a logic tester and will start testing RAM chips.
