Model: Bootleg Dyna Cherry Master
Symptom: Boots at random when powered on.
Board would not always boot when powered on. Would sometimes boot after sitting a couple of minutes.
Replaced bad reset switch and tested.
These boards use a toggle switch to "reset" the machine. It's not resetting the CPU, but rather whacking the battery backed memory by switching the +5v power pin to ground to clear it. It crashes the CPU when this is used while the board is powered on. If the switch is bad and not supplying +5v when the machine is on then the machine will do random, crazy things.
