#131788 - a footnote
Responding to: ???'s previous message
When 'homemaking' PWBs there often is a tendency to "think PWB" rather than to "think signals".

Make sure that the connections to the crystal and the burden capoacitors are SHORT and DIRECT. The same goes for the chip decoupling capacitors. You can get by with much, but that is essential.
