The HP-41 PPC ROM contains a routine called IG (InteGrate) which uses a modified Romberg, similar to the HP-71's Math Pac. Its code and some commentary can be found here: https://coertvonk.com/technology/hp41/integrate-4625

There are a few other implementations of Romberg for the HP-41 here: http://www.hpmuseum.org/software/41/41rombrg.htm

There are a BUNCH of various integration programs for the HP-41 in the "Differentiation & Integration" section of this page: http://hp41programs.yolasite.com/

Anybody? Anybody? Bueller?
