Do any of you old hp41 hackers have any on-line info about how bar codes are coded? I'd look in the library, but I am reeeaally lazy and I thought I'd just let my fingers do the walking, as it were. Thanks in advance for any information. ***************************************************************************** ** Bill Gribble Harvey Mudd College, Claremont, CA ** ** bgribble@jarthur.claremont.edu Never heard of it?

Bill Gribble asks: > Do any of you old hp41 hackers have any on-line information about > how bar codes are coded? Bill: On-line, no, but I have two copies of "Creating Your Own HP-41 Bar Code", HP's 80-page book on the subject (part number 82153-90019). One is yours, if you like. It's 8.5 by 11 inches, 10 ounces. Send s.a.s.e. to Joseph K. Horn / 1042 Star Route / Orange, CA 92667. But... WHY??? If you are thinking about HP 48 barcode, then DON'T use the 41 barcode scheme, which is probably the least efficient barcode scheme ever designed. -- Joseph K. Horn -- Peripheral Vision, Ltd. --

Bill:
Sorry, but I have no on-line barcode generation information, but you
may like to track down copies of the following manuals which should give all
the info you need ...
"Creating Your Own HP-41 Bar Code" HP Manual No. 82153-90019 Publ.1981
"HP 82184A Plotter Module Owners Module" Manual No. 82184-90001 Publ.1983
As these are old publications, I doubt if they are still available from HP.
Regards, johns

It can not make all kinds of bar code, only programs. The PPC ROM contains quite a lot of info on bar codes. >***************************************************************************** >** Bill Gribble Harvey Mudd College, Claremont, CA ** >** bgribble@jarthur.claremont.edu Never heard of it?
