Once again, the context of this Facebook review has been lost a bit, but I'm going to leave it as it was.
|Radio Shack EC-21.
The appropriately named Radio Shack EC-21 is more than just a calculator. If you've already looked at the images, this build up is pointless, but if you haven't, then you'll be stunned when you learn that this is also a gaming machine! The EC-21 not only handles basic calculations, but can also play rounds of Blackjack.

To play, simply slide the left slider to GAME and 0 will begin blinking. It's asking you to place a bet. You can bet however much you want, so I like to pretend I'm rich and bet $5. Press the bet button, and you'll be dealt cards represented by a single digit. It plays like any electronic game of Blackjack, but can be a nice distraction from a long day of math homework.
The one flaw that I didn't notice until I spent a few minutes with regular calculator use is the positioning of the equals button. Most calculators place this in the bottom right, but for some reason Radio Shack put it at the top, and not even in the right-most position. I found myself pressing the ( ) button, which is useless for most basic operations, and I had to clear the screen to try again.
The EC-21 was built in 1978 and runs on three AAA batteries. It comes with a nice leather case that also houses the manual. Nothing about it is complicated enough to warrant the need for the manual, but it's a nice touch. With its brushed aluminum exterior, It's a beautiful calculator, even without the case. I found it at Goodwill for probably $3.
