	Old German Addiator (Site not responding. Last check: 2007-11-07)
		I have a calculator that I used many years ago as a child, and decided I would like to know it’s history, but I haven’t been able to find anything about it.
		On the Vintage Calculator website is a picture of an Addiator called a Sterling currency model, probably about 3 1/2 by 5 inches in size.
		I imagine that this piece was produced for the purpose of sale within Germany rather than for export.

		Either the other pages got lost, or they thought the addiator was self-explanatory (it isn't, but you can figure it out pretty quickly).
		The Faber slide rule portion is infinitely more advanced than this crude thing, but aside from a more rakish-looking stylus, the only difference on the addiator face is the Faber name, fl colour scheme, and the lack of the "Made in Japan" label.
		According to Dieter von Jezierski's book, the addiator was actually invented by Carl Kubler, who received a German patent on it in 1937 and made it available for Faber rules.

	Edwin Russell's Virtual Calculator Museum
		This is an Addiator (it included a stylus which clipped into the 4 lugs on the right).
		Slower to use than the slide rule, 4-figure log tables gave a resolution of at least 0.1% and 5-figure tables were 10 times better.
		However you still had to manually add the log numbers, possibly with an Addiator, and then look up the result, so it was vulnerable to "user" errors.

		I've used an addiator, and now that I see the image I recall that you input the first number with a stylus, then input the second "on top of" the first number.
		The resulting sum is displayed at the top.
		To imagine a Turing Machine, think of an addiator, but instead of being designed to add, it's a universal machine, one that can perform any sort of calculation that you can describe, or almost any sort.

		Steve, I've been using Yahoo's translation feature and my high school German to read the very good and through history of the Addiator by Friedrich Diestelkamp.
		Now as best as I can make out "PUTTY" was the nickname of the daughter of Carl Kuebler (the owner of Addiator) and was the name of a brass version of a cheaper Addiator model called the PERPLEX.
		John Huey I have not seen one of these on eBay or anywhere else.
