I think the rear headphone output is the culprit, anyway. On the internal speaker I don't hear the polling sound (a faint "plopping") at all.
The reason you can't hear it on the internal speaker is that the internal speaker has essentially no response to low frequencies--it is a high-pass filter. The headphone output is the same signal (except for the possibility of a different level of "ground noise", which could be an issue here, too). -michael New Applesoft BASIC interface for NadaNet networking!
