Canon F-802P
The F-802P is a multifunction programmable calculator that's functionally equivalent to the Canon F-800P; the only difference is the form factor.
The F-802P can be characterized as a fairly high-end, "do everything" scientific model. In addition to the typical compliment of scientific functions, it also offers two-variable statistics, unit conversions, a constants library, probability functions, and last but not least, a programming model that corrects many of the shortcomings of earlier, similar models.
With 128 partially merged programming steps, even complex algorithms can be easily implemented. If only this beast offered a means to view/edit programs! As things are, if you make a mistake, you have no choice but to reenter your entire program again. This also makes experimentation difficult; your best bet is to use pencil and paper first, while you work on your algorithm.
This machine's programming model is best illustrated by a program I originally wrote for the Citizen SRP-80, which computes the value of the incomplete Gamma function. With the integration limit stored in register 0, and an argument in the display register, you can invoke this program by RUN 6. A large enough integration limit will let you compute the Gamma function itself accurately:
