I have received some e-mail about the audio filter in A1000. It is true that
the audio filter in A1000 cannot be turned off with software but, according
to the mail I received, there has been in some issue of Amazing
Computing instructions how to get rid of the filter in A1000 with a
little hardware modification. In A500 and A2000 it can be turned off
by software. There are some public domain -programs for this purpose, e.g. LED.

Anyone of those who e-mailed me about this subject didn`t remember
the specific date of the Amazing Computing in which those instructions
have been. Maybe somebody could post the information about that.

Thanks to everybody for mail!!
