The most potent info for my RPN toolkit has been the 'Algorithms for RPN Calculators.' The tips in its favour are:
1--a section which analyzes the various entry methods also includes a list of 250+ stack manipulators to produce any combination of X, Y, Z and T values in the stack.
2--Another part of that book features some quite essential RPN forms for the various algebra, logarithm and trigonometry identities which are keystroke efficient.
3--As the book progresses, various application programs are featured in Statistics, Mathematics and Engineering. The algorithms are so well clarified and notated that they can be translated easily into programming code. For example, loops are so marked that you can see where the loop begins and ends and that way, DSZ/ISZ or conditional branching instructions can be simply implemented around the algorithm for programming anything from an HP-25 to HP-48 depending on memory of the calc, of course.
This book is still loitering around on Amazon and eBay.
My second choice is the TK Enterprises 'Everything You've Always Wanted To Know About RPN...'
Like 'Algorithms,' the analysis given to RPN in addition to the history of Lukasiewicz's method is detailed.
Afterwards, the book is a vast application library which, like 'Algorithms...' can be transformed and modified for HP-calc applications.
There is also a reference in the back for the formulas used example calculators base instructions. For example, on the Corvus 500, there is a hyperbolic polar<-->rectangular function. So, as the appendix lists the Corvus 500 built-ins, the formulas are also listed. This gives the opportunity to implement some of the unique Corvus functionality into another machine.
If you put 'Everything RPN' (omit apostrophes) into Google, the first listing that appears is the PDF of the book which can be freely downloaded.
