I just bought an HP-71B, because of the EPROM in it. Turns out it's not an EPROM. It's a ROM. And it has a program that turns the 71B into an RPN calculator. DEFINED keys and all. Also might have some sort of programming, since it has an editor and REPORT function.
Now, to ID the program. The basic program seems to be WBLEX or WB. Here are the programs on this ROM chip:
WB (BASIC)
TED (BASIC)
RPN (BASIC)
WBLEX (LEX)
REPORT (BASIC)
PRINTWB (BASIC)
SORTWB (BASIC)
PORTER (BASIC)
FINDER (BASIC)
TEXTUTIL (LEX)
Anyone recognize the program? I have begun by executing RUN RPN and it does run RPN calculator mode, with redefined keys. Have to decipher the template for this and will report back. It's protected fits into a 32K ROM.
