Ahh, hmm.  I'd rather do this in software, but I
couldn't find anything useful on google when I
searched for it.  I'm not exactly sure what I'm
searching for either, which could be the reason why I
couldn't find anything ;-)

Yea, I would've used one of those LCDs, but the
project I'm planning on doing is going to require
quite a few pins from the microcontroller that is not
just for LCD.  Since the 2051 only has 20 pins, it
makes adding other components to the microcontroller
with a LCD that uses half of the available pins a bit
difficult.  Thats why I went with the serial LCDbug.

Thanks,
J Silverman
