This revision of the book has updated several things:
1) Algebraic instructions and program listings for the 12c platinum. Interestingly, some of these are shorter than the RPN counterparts.
2) Dates updated from the 1980s to the 2000 era.
3) Stock portfolio program now accepts prices as $40.16 rather than in 1/8's or 1/32's.
4) Brand new (to the book at least) Options pricing program.
The team that worked on this included me, Tony Hutchins in New Zeland and Luiz Viera in Brazil.
