Probably a stupid question, but seeing as I am getting back into the era of board jumpers and what not. I was curious if it would be possible to change a chips multiplier (and other things like voltage) on the fly while the machine is running. My idea revolves around some mad scientist hodgepodged switch panel I could put into a drive bay or something and it would have toggle switches attached.
Using the long jumper cables I got off ebay, you could maybe wire up some weird mad scientist shit. Now I know from testing you can't just have two ends connected to the board headers. Even if they are independent once contact is made on both header pins, on the power header for instance, the board will fire up. So I suspect the CPU multiplier jumper would work the same way.
I have 0 electrical knowledge so I'm curious exactly how it is board headers work. I mean its a piece of metal, waiting for metal contact. But what is stopping you from soldering some wire onto the jumper and using that to close/open a circuit? How does the board know the difference between "this is a short pin" and "this is a short pin with a wire attached, but actually I see metal making contact on both pins so I'm gonna do some stuff".
Do board setting jumpers work slightly differently from the main headers like power, reset, etc. I mean the reset switch header seems like its an open circuit that implicitly requires a push button toggle to create a closed circuit. Are board setting jumpers perhaps the same way?
Is it possible to rig up anything at all that would be able to attach to board setting jumper pins, and activate different combinations?
Sorry if none of this makes sense. I have weird ideas sometimes 😢
