USB OTG Kills Time during Calculus Class

Putting anything in the hands of bored students can turn from its legit purpose into their classroom toys. What do we have here today? Oh, it's a Texas Instruments TI-84+ advanced calculator that interfaces with a variety of peripherals ranging from a flash drive to a mouse via USB OTG. As long as the device draws 100mA or less current, the calculator will gladly welcome the new 'slave.' If you ask for what purpose, this video shows a scene from The Matrix playing off a 1GB Lexar drive on the TI's monochrome screen in what seems like ACSII style. Students can also exchange games using a thumbdrive as the cal has no Bluetooth. Now, we know why TI rolled out the high-res like the TI-89.
