It is really neat. I wish pictures showed it better, there is nothing like seeing them in real life.
My dad got an LED TI multifunction calculator for a Christmas present way back when I was just a toddler. I recalled that some calculations took up to two seconds to process. And I think its price was in the $200 range. I'm guessing it was comparable to today's faster and cheaper TI-30 line.
I was going to make a little video of my "money manager" calculator, mostly to show it "thinking" and the time it takes. I can't seem to get it to store any numbers to do the payment calculations though. I would think this would be one of the most time consuming calculations it can preform.
It's kinda weird, the calculator works fine otherwise, so I don't know why it wouldn't store the numbers.
I did find out it was made in late '77. There is a manufacturing stamp on the back.
So, no video, sorry. It does take about 0.75 seconds to do some log and e
x calculations, but that doesn't seem
too exciting.
i don't know anything about old calculators but maybe it takes a battery to store the numbers?
