To close the loop, I messed up. Long story short, I lost an IC pad and got solder onto where it should be so I think I'm hosed.

Tips for beginners like me (I learned soldering only because of this EEPROM problem) so you don't make the same mistake:[LIST][*]Watch this vid, go to 3:00, notice how there's solder behind the leg (the heel as the video calls it). Remember to get this spot when trying to de-solder the original chip. Also just watch the entire video; it's good info for how to solder on the new chip[LIST][*][URL]https://www.youtube.com/watch?v=Nq5ngauITsw[/URL][/LIST][*]Don't...

I happen to be starting the process to replace my EEPROM so made the measurements. Haven't replaced the EEPROM yet. I measure R19 = 3.76 kOhm and R20 = 4.70 kOhm...
