And this is a tall order, mind you...

Interesting question! So I just plowed through the HP-71 Math Pac Owner's Manual, and the only things I found which I don't recall seeing in the HP Prime are these:

NEIGHBOR(X,Y) [nearest machine-representable number to X in the direction of Y]
LOG2(X) [same as LN(X)/LN(2)]
SCALE10(X,P) [same as X*alog10(P)]
NAN$(X) [Prime doesn't seem to have NaNs with embedded error codes]
PROJ(Z) [It seems that Prime does not support complex infinity]

But all the real meat-and-potatoes functionality of the HP-71 Math Pac is certainly present in the Prime.
