Casio fx-7400G
The fx-7400G is a standard graphing calculator from Casio.
The program example here, another implementation of my favorite the Gamma function, demonstrates many aspects of this machine's programming model.
"X=":? -> X 1 -> Y Lbl 1 X >= 0 => Goto 2 X×Y -> Y:X+1 -> X Goto 1 Lbl 2 e(ln ((1+(76.18009172+9.5E-9)/(X+1) -86.50532033/(X+2)+24.01409824/(X+3) -1.231739572/(X+4)+1.208650973E-3/(X+5) -5.395239384E-6/(X+6))× √(π×2)/X)+(X+.5)× ln (X+5.5)-X-5.5)/Y
