Summation based benchmark for calculators

[TheKaneB]

Speaking of little laptop-thingy. I unleashed my trusty Olivetti M10 (similar to the Tandy Model 100).

With 10 iterations I got about 9.5 seconds
With 100 iterations about 91 seconds

It has 14 digits, but I used a 12 digits approximation of "e" (copied from my Prime), so the result is a bit off.

This thing has a 8085 CPU and runs Microsoft Basic
