11/23 clock issue

I've not meant that Noel should design his own CPU board and should left unused inputs open or connected to Vcc. I've don't wanted to discuss design considerations, I've stated this more then one times so I don't understand why People here trying to mark my post as faulty, regardless if my post has only todo with repair purposes. Maybe the '240 is be bad and the fault is only found if one connect it with a resistor to Vcc but such faults don't happen in reality or "not likely". One has just to point me to a '240 with such a fault. Yes, I know, all kind of unusual things could happen with semiconductors if they get bad, but what the heck should Noel do to repair that thing? Should he look with en electron beam microscope to the chip? To which chip? Maybe the Oscillator is ok, but a copper trace on the pcb is burnt since a tantalum capacitor has a short... maybe.. Remember, the '240's input was floating at approx 2 Volts, that's the normal voltage that someone wil find on a life chip with an open input. But why the heck you are trying here to find all kinds of unusal causes only for the purpose that one cane state: "Holm's hint is bad!"? I've tought that we are here for fun with old computers and repairing old electronics and to help each other. I'm wrong it seems. Sorry Brent, sorry Peter, the only thing that you are reached now is that I'm now in the asshole mode, giving back what I've got here and since you aren't interested in my opinion about your persons, why sould I worry about yours about me?
