I tried it on the TI-59 with the stock library module, and after 15 minutes I gave up and turned it off.

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...

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) RE: So, I bought a 41CV - Massimo Gnerucci - 01-21-2018 12:28 PM (01-21-2018 02:53 AM)Joe Horn Wrote:(01-21-2018 02:36 AM)Massimo Gnerucci Wrote: Yep!

[attachment=5623] RE: So, I bought a 41CV - TheKaneB - 02-01-2018 05:33 PM 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 - salvomic - 02-01-2018 06:13 PM (02-01-2018 05:33 PM)TheKaneB Wrote: ...The display looks in perfect conditions, and overall I'm really excited to study it in detail in the following weeks happy! enjoy it, Antonio. ;-) RE: So, I bought a 41CV - TheKaneB - 02-01-2018 10:50 PM 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 |
