I don't know if anynoe has run up against this yet, but there seems to be
a significant (at least for me) problem with the units functions on the
HP48SX.  I have rev D ROMs, and what I get is that:

             1_C^.5/F^.5    !=     1_V^.5

               ^    ^                ^
               |    +- Farads        +- Volts
               +- Coulombs

Now, unless I am off my rocker, this is wrong.  The really frustrating thing
is that it appears to work properly when using the NMOS Transistor equations
in the Equation Library, but if I reconstruct the exact same equation with
the exact same units outside of the library, it doesn't work.  Does anyone
know what is going on here?  Any help would be GREATLY appreciated....

By the way:  What I am working on is a more detailed version of the eqs
in the equation library for semiconductor devices.

                             Anyway, thanks in advance....
