Of course, Yrrid's TTYDSP can blaze at 128kbs on a lowly '030, or even an '040!
And with 3.0 handling a lot of the sound work in the 680x0 processor when the  
DSP is busy, there's little, if any, penalty!
My '030 uucp/print server handles 56kbps without a hitch!  Since the '030 is a  
'little' slow, it had trouble playing the various printer messages without the  
DSP available, but I used sndconvert to change them to 16 bit 22050Khz streams,  
which takes less effort to play, and the '030 speaks clearly again!
