Speed of the hp calculators family

[Jim Horn]

Good point. But today's speeds are a real help. I worked hard to get the HP-67 to be able to factor any input value within its integer range (up to 10^10). The worst case, 9999999967, took about 3 3/4 hours as I recall. And its battery pack seldom lasted that long on a charge.

That the WP 34s can do that in a fraction of a second is *very* much an improvement!
