HP-32SII :: Hewlett-Packard RPN Scientific Calculator

What this page is about

I set up this page to see if I could find any other HP32/HP32S/HP32SII
enthusiasts (that is, geeks). I had a great HP-15C when I was
in University, but alas, I could not find another when it came
time to buy a new calculator (I sold the 15C like an idiot).
The HP32SII seemed to fit my bill. It was RPN, programmable,
and had a lot of the same features of the HP15C.

Sample Program
Euclid's Algorithm for the Greatest Common Divisor

  ; This is an HP-32S version of Euclid's Algorithm to find the greatest common divisor.
  ; You run this by putting the two numbers for which you want to find the GCD and pressing "XEQ E"
  ; I'm modifying this to put the non-shifted
  ; key in brackets next to the shifted key
  ; to make it less confusing. (Thanks, Stefan)
  ; Where I say oShift, I mean hit the orange shift key first
  ; Where I say bShift, hit the blue shift key first
  E01 LBL E     ;[oShift +]
  E02 STO A
  F01 LBL F ;[oShift +]
  ; Divide y register by x register
  F02 ÷
  ; Get the Fractional part
  F03 FP ;[bShift square root]
  F04 RCL A
  ; Multiply the fractional part by the first number you put in
  F05 x
  F06 1
  F07 x>y? ;[oShift ÷] then select >
  F08 GTO G ;[oShift XEQ]
  F09 R(DOWN)
  F10 PSE ;[bShift R/S]
  ; Exchange the x-register with STOrage A
  F11 x <-> A ;[bShift x<->y] (next to ENTER)
  F12 RCL A
  F13 GTO F ;[oShift XEQ]
  G01 LBL G
  G02 RCL A
  G03 RTN
