[VA] SRC #012a - Then and Now: Probability

[Albert Chan]

Running Emu71/Dos under DosBox is slow, with bad timing info.
Running it in WinXP is faster, with more consistent timing.

This despite my Toshiba laptop is supposed to be 10x faster than my 22 years old Dell ... go figures.

HP71B codes so far, running in Dell Optiplex GX110 866MHz, with 512M Ram
All codes adjusted to return only P(R=30,S=60), and time needed.

Timings from best of 3
Symmetry of Yes meant starting condition must be symmetric.
