Yes, just tried it out. And if the "decimal" switch is turned on, you get "____._0" as result istead :-) I wonder why anybody would want to use such a device, even in 1973.

Why? Price. With all of these cost saving measures, this must have been one of the cheaper models available at the time. I saw listings where it was advertised at US$24.99 in April 1974 and was on sale for $14.99 by November. And if you only needed it for balancing your checkbook or very basic math, it would work for that.

I remember looking at limited models like this around 1973-1974 as I was trying to convince my mother that me buying an electronic calculator would not ruin my ability to do math with pencil and paper. Those were dark ages indeed.

Here is more information on this model including the "manual".
