Question: Can a person piggyback 2101 RAM "on the fly" ... meaning can I install/remove the RAM while the game powered on to test or is it best to power down, piggy back, power up, check, power down, repeat if necessary with a different location?
Heck, if a pro would go through the generalities of a PCB as far as what you can touch and what you should avoid I know I would appreciate it. I always have treated the majority of a PCB as a "hands off" while powered point of view... how accurate is this? What can and what can't be touched/tested/etc with bare hands?
I've always treated electrical items with an abundance of caution. That said, being that most PCBs run at 5VDC, I imagine I am being a little more paranoid than necessary? Can a finger "bridge" legs of an IC by accident (for example)?
