The circuit could be made using nothing but relays. Or it could be made with a single eprom and some caps. Or transistors and caps. Or 74xx logic chips like flip flops. Or a MCU chip or CPU based development board. I think I could do this with pneumatics too. Perhaps mousetraps and strings too. What happens if someone repeatedly presses just one button or two buttons? If someone presses the first button, does it wait forever for someone to press the second button or is there a timeout. Etc etc etc. State diagram would be most helpful.
