Casio fx-8000G
The fx-8000G is a second generation graphing calculator from Casio. It is larger than the fx-7000G, has more memory, and it has a data expansion port, that lets it to be connected to an FA-80 cassette/printer adapter. Yes, this calculator represents a peculiar era: it was the PC era already, and a parallel printer with a Centronics connector was not at all an unusual accessory, but it was an era that preceded the standardizedPC; hence, rather than providing an I/O capability that would let you transfer files between your PC and your calculator, the designers opted for an interface to an external cassette tape recorder for program storage.
The program below demonstrates the programming model of the fx-8000G by implementing the Gamma function using an accurate version of Stirling's approximation:
Ans->X 1->Y Lbl 1 X>5=>Goto 2 XY->Y X+1->X Goto 1 Lbl 2 Xln X-X+ln (2π÷X)÷2+ ((((1÷1188÷X÷X-1÷1680)÷X÷X+1÷1260)÷X÷X-1÷360)÷X÷X+1÷12)÷X-ln Y
