The sophisticated HP-65
Even with 100 semi-merged steps and nine (eight if you’re using functions that need R9), the HP-65 can definitely be a strong programmable.
So, what is the most sophisticated program you’ve written for the 65? |

RE: The sophisticated HP-65
I managed to do all 6 hyperbolics and inverses in 100 steps accessed through spelling out the function with the 5 soft keys as “arc”, “co”, “sin”, “tan”, and “sec.”
I’ve tried getting a two variable stats package using a common summation logic and merge-able cards but haven’t quite figured out how to squeeze out a few more steps yet. |

Up to now, the most sophisticated program I write for the HP-65 is concerning the position of any rational in the Calkin–Wilf tree. It was a part of the numerous exchanges and works-out from the MPO96 challenge in the french forum www.silicium.org (Sept 06,2020). Label A is used to calculate the index of U(n) from the rational A/B (the GCD is in register R2 at the end of the calculation): a [ENTER^] b (A) displays U(n) . Label D makes it possible to determine the rational A/B from the index of U(n): n [ D ] displays A then [SST] displays B. |

RE: The sophisticated HP-65
Everyone should check the early issues of the PPC Calculator Journal (what? you don't have the PDF copies of all those issues? - it's on the HHC conference drive and Jake Schwartz sells the scans cheap!)
Whole issues devoted to game programs as well as incredible non-games too. |

I have to change my practice when posting; copying and pasting my code from an emulator or a quality simulator will avoid the far too many errors and typos I made up to now! I'm updating all of this... |

RE: The sophisticated HP-65
Cramming the N-Queens benchmark into 100 steps and no indirect addressing is probably the tightest fit I've pulled off.
(Also see the link at the bottom of that thread where Thomas Klemm managed to make it work on the 25!) |

This is the reordered program: Code: 001: 23 : LBLA single test using 11113 with the emulator would indicate this. |

RE: The sophisticated HP-65
No problem...
My project is to continue to illustrate the listing of my programs with as much information as possible to understand the ins and outs, the methodology and how it all comes together. But, I still will try when possible to copy-paste the codes and mnemonics from an emulator or a simulator. This will limit errors (too many for my taste) due to inattentive transcriptions of my notes. Especially when I compose the program by improving it on a real machine. I agree, color and layout are of great importance and cannot be changed, a lot of documentation here follows the same style. To illustrate: |

It's not just 100 steps as this is a mag card programmable; a virtual machine. Better to ask how many cards were used. As for me it's a 4 card set to solve the Barrowman Equations. -J |

RE: The sophisticated HP-65
A couple interesting relevant points:
I had several programs accepted into the 'HP65 Users Library' back in the day. Also, while in a numerical methods class (in the days of Fortran IV on an IBM1130 mainframe), we had a 'drag race' with my HP65 for estimating Pi via inscribed and circumscribed polygons. While not a particularly sophisticated program, it uncovered the numerical accuracy superiority of the precision of the HP65 compared to Fortran of 1975 (I do not recall if I used single or double precision). After this experiment, my Mathematics and Engineering profs ceased making fun of me carrying and using that expensive 'toy'!
