RPN on a pocket computer

[SlideRule]

An excerpt from TRS-80 Microcomputer News (volume-4, issue-9), October 1982, pages 40-43

"    For all you Reverse Polish Notation lovers, here is a program for the PC-1 pocket computer (PC-2 changes follow the main article) that will replace the old Hewlett Packard you threw out! It is an almost perfect simulation of an RPN Calculator, and includes a register shift key, an "exchange X and Y register" key, keys to store and recall up to 38 numbers (in the data memories), and all of the functions you would expect to find in any self-respecting calculator. Oh, and there is a quadratic notation equation solution program, as well. "

BEST!
