The obvious question is, is calculation set to automatic? Less
obvious...are there any linked pictures (linked to ranges in particular)?
Is it slow manually entering data, or is it just by macro?

Is the speed (even for such a small list) that much machine dependent? I
am using a Pentium III 386...

Of course machine speed is an issue. But a 386 and a Pentium are different
machines. I had a 386 in 1988 so I'm hopeful that's not what you have.
