Indeed they do. And even if you have working chips you get the next stage: board level reset bugs. A MC68K board I helped develop didn't want to boot, some nasty side effect of a reset line that didn't stay at the same level long enough stopped the CPU from resetting reliably when everything else did just fine. That took a while to debug.
