Attached is the PDF - Valentin, let's see if you can read this. :-) It's somewhat interesting, but the speed will be affected a lot by the FOR...NEXT's which we already knew are slow, and line-number searching, but the benchmarks don't do the trig, log, and matrix operations which is where I think the 71 would shine. My longest-running project ran the 71 for weeks to calculate large tables for math functions and produce 6MB of Intel Hex files, but I suspect that a major thing slowing it down was all the text and occurrences of HTD and DTH$.

I agree. I was never able to develop any liking for that CALC mode. It's pretty worthless to me. http://WilsonMinesCo.com (Lots of HP-41 links at the bottom of the links page, http://wilsonminesco.com/links.html ) |
