HP-71b ROM version

[rprosperi]

There is lots of useful information about the 71B and 71 HP-IL module ROMs on Jean-Francois Garnier's (often seen in these pages as "J-F", "JFG" or "Jeffcalc") website here:

Although it may appear from reading these notes that the 1BBBB and 1A have lots of bugs, they are both generally stable and usable for most tasks without fear of losing data. That said, a key one to know about, if you plan to create and use LIF media, is HP-IL bug #3.

Enjoy your 71B - it's a great machine!
