Something I've learned is that modern CMOS logic is a lot more forgiving than TTL for breadboarding, thanks to low power consumption and push pull outputs. So if you're thinking of b'boarding a classic circuit like a minicomputer, allow yourself one concession to modernity, namely using something like 74HC logic instead of 74LS.

I have to agree there. 74hc is surprisingly robust!
