If it's a clocking problem, you be getting Pod timeout errors
rather than power fail errors, wouldn't you? It's most
likely that your LM309 is sagging just a little. If you
disable power error trapping, you'll probably be fine. It's
not a problem endemic to Night Driver boards, as we've
done quite a few and never had the issue you are describing.

How could you do that without bypassing the LM309?
