Hiya Chuck, I've got the two top ones and I'm listing top left as TCR N4783 B value ($2 C/W) and top right as TCR N7869 B (2/4/6 C/W). Campiglia/Wells puts the bottom chip as last issue which I'm guessing may be the current chip at Union Plaza, B value. Couldn't find bottom chip in 8th edition of TCR because, well, it's not in there!
