I managed to find a small SSD relay from Curiosity Tech. Basically it has 4 wires, 2 for + & - constant, two for the button that is to be pushed, and one for trigger. I figured I could use this to power on the second system, but not 100% sure how to do it. I figured the constant power can come from the OPUS 12V rail. What I want to know is what should trigger it? I was thinking of maybe having the MZ setup so that it turns on when power is applied. Then the relay only sends a signal to shut down. God, why are things so complicated, lol.
