Some programs for the hp48sx are available on calvin.stanford.edu.
Most of these are programs that I have gotten from
hpcvaaz.cv.hp.com
gmuvax2.gmu.edu
funic.funet.fi

Since I am posting anyway, does anyone know the internal hardware of the
hp48sx.  I know about the processor, and the assembly language, what I
would like to know is the I/O of the processor.  How does it get key 
presses, do serial I/O and display to the screen.  Any help would be
appreciated.

Thanks,
Andrew
