Texas Instruments TI-80
The TI-80.
Here is what a program that calculates the Gamma function for any real argument looks like on the TI-80:
:INPUT X :1->Y :LBL 1 :IF X>=0 :GOTO 2 :XY->Y :X+1->X :GOTO 1 :LBL 2 :e^(LN ((1+76.18009172947/(X+1) -86.50532032942/(X+2)+24.01409824083/(X+3) -1.23173957245/(X+4)+1.208650973866E-3/(X+5) -5.395239384953E-6/(X+6))√(2π)/X) +(X+.5)LN (X+5.5)-X-5.5)/Y->Y :DISP Y
