Thanks! I just listened to the opening few notes of Star Trek [!]
But very faint and I don't know if the dinky BEL is a chip or a

Probably help to be a dog! --That reminds me of what my parents

Def !fun, but not rocket science either. I'll poke around at this

I've found spkr.c; still there after all these months, :)
thanks again,

PS: this might be interesting: I just tried to get
% xset c 50
and
% xset on
on my Ubuntu Thinkpad. Zip. At least here I've got the code!
