Hmm. Ah. well.. I think I got the problem.. It isn't a bad connection,
it isn't a popped out chip, it's the power supply.

You know... I checked it, really! Located the first 74LS*** I could find,
located GND and VCC, checked it, et voila: A nice 5.00 volts.

How the **** could I know that the thing has two seperate 5 volt 


(Oh yeah. Because it has two 7805's.. Hmmm..)
