Can we have RPN back?

[Matt Agajanian]

My turn.

As an old-timer, I vote for our traditional 4-level RPN (Woodstock and following) implemtation, with the additional HP-45 RCL +-x/ functionality for several reasons:

1--it was functional, versatile and poweful enough to merit usage of an HP-65 on the Soyuz mission

2--As per the 1982 HP calendar, several others 4-level RPN HP calcs were utilised in events such as America's Cup Yacht Race among other events.

3--A cadre of HP-41s were on board Sally Ride's missions.

4-The over 30 HP-67/97 and over 30 HP-41 Application Pacs in various disciplines from Mechanical Engineering to Biomedicine to Civil Engineering to Statistics and so forth.

5--Even now, with both the HP-12C and 35S, it stands to reason 4-level
RPN is still robust, versatile and efficient.

6--Extended functionality of RPN is enhanced when applications and stack manipulations from John A Ball's 'Algorithms For RPN Calculators' and the TK Enterprises book 'Everything You've Always Wanted to Know About RPN' are put into practice.
