Alright, so...I have like, a few logic ic chips and none of them work right at all. I have a 4077, 4093 and m74hc03b1r (quad nand) and each one, quite "reliably", doesn't seem to respond. Is there any special instructions? Do the inputs require a certain signal or something? I am just...disappointed. So many things I could do with logic...if I could just get the darn things to work. Any ideas?
I use an led on the output and it lights up at first (or doesn't...depending on the logic) but when any of the inputs go high, either nothing happens or whatever does happen doesn't follow the truth table for that particular logic. This is highly aggravating.
