Summation based benchmark for calculators

Thanks, Mark. Posted this over there.

I am VERY impressed with the DM-42. This crash is concerning :-( but the only other item of ANY kind is that the square root symbol on the key is markedly to the left of centered. It's pretty obvious that it is off-center. Love my little machine. Time to get .raw files of any and all HP 41 programs in a file area so they can be loaded...especially BIG long game files.

Well, games and math functions not built into the DM-42. Think statistical distributions and a lot of the material in Sandmath for the 41.
