HP-71b ROM version

[Valentin Albillo]

Hi, joved:

Like Bob Prosperi says above, version 1BBBB of the HP-71B ROMs is perfectly usable and despite many bugs being listed for it, I've never been bitten by any of them in ~40 years of using it daily and extremely extensively (thousands of lines of code), so I've never found the need to "upgrade" to another version.

Perhaps you'd like to have a look at some the code I've created for it; you'll probably find it very useful to see what the HP-71B can do and to have a sizable amount of optimized HP-71B BASIC code to learn and use new advanced techniques. These are the links:

Long Live the HP-71B, (full description and history, includes a Text Stereograms generator program)

HP-71B Short and Sweet Sudoku Solver, (program to solve any Sudoku puzzle)
HP-71B Sudoku Solver Sublime Sequel, (enhancement to the program to solve any Sudoku puzzle)

HP-71B Minimax Polynomial Fit, (program to fit a set of data to the very best possible polynomial)
25 years of Othello, (program to play Othello (aka "Reversi") versus the machine)
Small Fry - Primes Acounting, (routine to very quickly count primes on a given interval with excellent accuracy)
Small Fry - Let's Be Rational, (routine to convert reals to fractions and find their continued fracton form)
Boldly Going - Matrix Square Root, (routine to compute the square root of a given matrix)
Boldly Going - Identifying Constants, (program to find the symbolic expression which evaluates to a given numeric value, many applications)
HP-71B Advanced Uses of STRNGLEX, (focuses on its less known keywords, whose capabilities are described with examples aplenty)
