All

Correct. Though in a 40/120 game, it is not too important if operator time is 5
sec or 10 sec. It's just difficult to have two machines hooked up to
loudspeakers so you're not missing anything.
Especially bad are programs which emit sounds over the internal "beep" function
instead of the audio device (all DOS programs do this) - on my P6, the beep is
very loud, but on the PIII's it's barely audible when the TV is on or you're
talking to someone. :(

Correct, but if you always shut down when White has moved, it is as fair as you
can get (if you take care that a program plays just as many games with White as
with Black during a tourney).

I think these problems are really of minor impact when using a time control of
30/game or more.

Why? I have not had any problems with the clocks; almost every program can save
them precisely to the second (Nimzo 98 being the only exception that I can think
of).

Even more if you have only one monitor and need to switch input sources before
entering the move... :(

But with all that has been said about Auto232 problems, you're just replacing
one error source with another, and one that is almost out of the operator's
control.

Besides, I think that the "PB off" timing problems Bob described are probably
almost non-existant in Blitz.
