Electroplay Quickfire (1979).
It's a toy from my childhood, my memory of it rosier than the actual game. I didn't remember the title or manufacturer until I stumbled on it a few weeks ago. Not knowing the MCU, it was an expensive gamble to purchase it, but I did it anyway. It's a TMS1000, Sean Riddle decapped the MCU and traced the PCB. And now it is emulated in MAME.
