So I'm working on fixing my newly acquired quadrapong and have a few questions. I think that I've narrowed down the problem to my clock circuit. I've probed different parts of the circuit and have a feeling the clock is the problem. My question is if the clock circuit is supposed to produce a 5V square wave right from the crystal oscillator? Right now the circuit goes through two back to back hex inverter gates and then through a flip flop. When the signal comes to the flip flop it is only reading 2 volts peak. I read the data sheet and it said that the 7404 hex inverters only needed an input of 2V in order to trigger. What I'm finding strange is that they are only outputting 2V also. I'm attaching a picture of the output of the flip flop.
