I like the sneaky footnote: Addition loop test, completed in HP labs. Up to 100X faster than original HP 15c. "For at least one pair of numbers, we can perform a single addition about[1] 100 times faster than we could in 1982." Did any of the original owners complain about its addition speed? I'd have thought the matrix operations and numerical integration would be the slow bits. I wonder if you could get this speedup just by better fab technology and upping the clock rate, or if you'd need to go as far as bumping the process size down a notch or cramming stuff closer together. Edit: it's a limited edition, so presumably they're not doing anything too complicated. I wonder how much a new set of masks cost these days. [1] if it was more, we'd boast with that number!
