"Extend your HP41" is a better primary source.

Certainly as the original book on synthetics, Wickes' book is dated, but I enjoy the way it explains the discovery and building of the jumper, etc. Later books (Jarret's and Wlodek's in particular) definitely explain more powerful techniques, but I still enjoy Wicke's style best. Tastes vary...

I like it too, and it is such a remarkable book that was available so short after the release of the HP41, about one year?

It is well worth studying, but more discoveries were done after it, and the system grew with extended memory, HP41CV and the HP41CX, as well as many other things. By the time of "Extend your HP41", lots of internal documents had been made available by HP, allowing for further insights, though it focuses on the user code side and the system.
