I tried it on the TI-59 with the stock library module, and after 15 minutes I gave up and turned it off. http://WilsonMinesCo.com (Lots of HP-41 links at the bottom of the links page, at http://wilsonminesco.com/links.html#hp41 ) |

I judged it from memory and looking into it now, the HP-41 can really be twice as fast. Wow, it makes me even more impressed by the HP-16C, which currently outperforms my Ladybug ROM in some cases, though there are cases where the opposite it true. On the HP-41 side I have the benefit of more raw CPU power, but is hampered by the overhead of the more flexible (complicated) operating system and memory system. A challenge to tend to at some point... Håkan |

Will the Time module let me go back in time and have my money back?
Anyway, for me the speed is somewhat important, because I like to experiment with programming a lot, so if I have quicker results it means that I can do more experiments in the same timespan. However speed for me is very low in my priority list, (in order: keyboard quality, display, keyboard layout, user interface, number of functions, programming constructs, and then speed) Software Failure: Guru Meditation -- Antonio IU2KIY |

RE: So, I bought a 41CV
decoding the serial number it appears to be an early 1988 model, it's in perfect shape, with very few marks and the keyboard is just a joy. For some reason I was expecting a stiffer key action, but I'm pleased to learn otherwise. The display looks in perfect conditions, and overall I'm really excited to study it in detail in the following weeks

RE: So, I bought a 41CV
Hi Mike!
Thank you, but I'll try to resist the urge to read your code, since I wanted to implement it myself first When I'm happy with the result, I'll compare my code with yours to learn more advanced techniques Software Failure: Guru Meditation -- Antonio IU2KIY |
