How are we supposed to have a proper internet-style discourse if you're going to think this through? :) Sigh, of course you are probably right. Plus, the AA simulator is especially speedy because it only has to oscillate in neat circles. Probably operating near a mechanical resonance too. -- -bmw -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
