Sharp LC-8 / EL-8 - the $345 calculator
Here is a great old commercial for one of the first electronic pocket calculators. It was released in the 70s for around $350 which would be closer to about $1200 adjusted to 2008 currency. I think I'll stick with my TI-89. I've recoded this from the source to provide a better version than you can find on YouTube or other sites. Check it out!
