The circuit above goes to a "reset" state (no outputs high) only if you hit the correct switch when one output is high. A true reset switch clears all outputs without knowing which one is high. | |

The eventual PCB has a lot of power smoothing, and the chip will have a tantalum cap. This is great for me, it frees up a lot of space because the switches are momentary foot switches flush mounted on the PCB, and have a HUGE courtyard. Loosing a whole switch means I can comfortably fit everything on without using the reverse side of the board, which obviously saves me money too. | |
