    What a cool hack! I want someone to make a portable 2 color printer so I can run a tape from my computer calculator program. That way I don't need a separate calculator to print my calculations and go back and forth between the two.

    You fitted a USB storage drive to the case of a calculator. You are not powering a calculator from a USB port on a computer. You are not storing data from the calculator on the USB storage drive. You simply have a very large case for a USB storage drive that is also a calculator. Is that correct?
