TMS0803 scientific calculator emulated on MSP430G2452

simpleavr got inspired with web based calculator emulator and so he decided to build his own hardware based emulator. He’s chosen MSP430G2452 microcontroller (same that comes with launchpad) to run emulation.

He tried to match original calculator layout and speed by selecting MCU clock speed. To make it look more retro he used bubble LED seven segment indicators. After several PCB versions it seems that he finally made it.
