The HP 30b Business Professional

 

Gene Wright

 

 

What is it? 

 The HP 30b is Hewlett Packard’s new mid-range financial calculator.  This machine is a very 

welcome addition to HP’s financial calculator line.  The HP 30b comes with a very small printed manual, 
which certainly seems to be the continuing trend.  A larger PDF manual is available online as well as 40 
learning modules that go into greater detail on how to use the HP 30b.  This review will focus on the new 
features found on the HP 30b and differences between it and the HP 20b.

Physical differences.

  First off, the HP 30b uses rotate and click keys.  This is a welcome improvement 

over the HP 20b keys, which many found to be inadequate.  While the author never had any real problems 
with the HP 20b keys, it certainly is nice to have a good click when pressing a key.  Secondly, the HP 30b 
comes with a metallic-looking faceplate compared to the shiny black faceplate on the HP 20b.  Some of 
the  pictures do not quite do the real color justice – the real calculator color is more bronze/copper than 
pure silver as the picture would suggest.  The back of the HP 30b is the same black plastic as on the HP 
20b.  The HP 30b comes with a slip case to protect it.
