I know things have changed with the ICs since I last messed with them all, and I am logging on at the moment to test them.
For Mc0420 and MC3102, did you put down anything for line 3?
For Mc1020 and MC2020, well they are both random and require a clock input; Mc0420
EDIT:
I am not doubting Jonsoon, I am just checking to support his claim.
MC0420, does not work.
MC3102, do not have permission to use.
Fun fact, Mc1420, which is labled "counter" in-game is actually Clock divider
No point for me to test random bit ICs, they require the clock, which doesn't work.
