SHARP PC-E500(S): 106 keystrokes!

The SHARP PC-E500(S) blows most other calculators out of the water.

[LN] refers the LN key and [x^2] refers to the squaring key. [BASIC] switches modes. Commands are abbreviated as usual: I. is INPUT, P. is PRINT, G. is GOTO, and R. is RUN. Colon is [2nd];

The program:

Code:

[BASIC]                                      1 enter PRO MODE
1I.A[ENTER]                                  5
2I.B[ENTER]                                  5
3P.[x^2]A+A-[LN]B,[LN][x^2]B:G.1[ENTER]      20

The table:

Code:

[BASIC]          1 enter RUN mode
[PF1][ENTER]        2 run (function key 1 for RUN)
3.12[ENTER]      5
2.56[ENTER]      5 displays X and Y
[ENTER]          1 A is unchanged
B/2[ENTER]       4 displays X and Y
[ENTER]          1 A is unchanged
B/2[ENTER]       4 displays X and Y
2*A[ENTER]       4
[ENTER]          1 B unchanged displays X and Y
2*A[ENTER]       4
[ENTER]          1 B unchanged displays X and Y
2*A[ENTER]       4
B/2[ENTER]       4 displays X and Y
[ENTER]          1
B/2[ENTER]       4 displays X and Y
[ENTER]          1
B/2[ENTER]       4 displays X and Y
18.59[ENTER]     6
[ENTER]          1 B is unchanged, displays X and Y
17.63[ENTER]     6
[ENTER]          1 B is unchanged, displays X and Y
[ENTER]          1 A is unchanged
2*B[ENTER]       4 displays X and Y
[ENTER]          1 A is unchanged
2*B[ENTER]       4 displays X and Y

Edit: just realized that A*A can be [x^2]A and colon is [2nd];

Edit 2: ... oh well, so apparently the browser didn't scroll the table with the PC-1211 program and inputs I looked at, so I missed some inputs (there are 12 results, not 10, for a total of 107 keystrokes). Never do this kind of thing right before dinner time

Edit 3: saved one keystroke (now 106) by using function key F1 instead of R. for RUN, because F1 is by default RUN.
