The first pocket calculators came out around 1970. They had only the four main function keys, and cost $100.


Yep, I remember them very well. I am so amazed at how much further technology has come in the last few decades. It just seems to be rolling ahead at an exponential rate with each one that passes. I read old (1800's to 1950's) science fiction books and it is amazing how often the really good authors were correct (not necessarily about the year in which various things have happened) about where technology has headed. Thanks for the memories.
