1974 Texas Instruments SR-10

As I recall this SR-10 was the first affordable electronic calculator with some "advanced" functions. There was that HP model, but it was about 3-times more. This "advanced" model cost $150 in 1974 ($655 in 2010 dollars); the HP at $400 in 1974 was just too much ($1750 in 2010 dollars).

Well, it was a step up from those old coffee grinder adding machines we used to add up the expense accounts.
