Re: HP-71B System ROM Revision History Message #2 Posted by J-F Garnier, France on 5 Dec 2002, 6:34 a.m., in response to message #1 by Philip
There are three public ROM versions:
1BBBB is the first public version, and the most common,
2CCCC is a rare version with a lot of minor bugs corrected, but it also adds a extra major bug,
2CDCC, which replaced soon the 2CCCC version fixing the major bug.
In this forun, it was also mentionned a prototype version (1AAAA), or even earlier developement versions, but I don't have any information on them.
