Hi all - just a question to clarify my understanding of how the reset controller on a System 7 works. It takes two power supply rails, +12 unreg (via Q9) and +5 reg (via Q8). Both of those have to be good in order for reset to be high. But... why? +12 isn't used for anything else on the board, as far as I can see. And +5 reg is derived directly from +12 unreg in the PSU. So - why does reset depend on them both, rather than just +5?
Confused!
