Casio fx-200P
For a long time, I believed that the fx-200P was an early programmable calculator from Casio, using a vacuum fluorescent tube display. Its model number is, after all, just one digit away from that of the legendary fx-201P.
In reality, the fx-200P turns out to be a somewhat more mundane second generation programmable, using an LCD display and a programming model that is common to many later Casio machines.
This programming model is demonstrated below by an implementation of my favorite example, the Gamma function:
