If you have knowledge in this area, I would like to contact you. If you have pointers to books &/or articles &/or experts, please let me know. The problem: connect a bar code reader to a micro computer. The term "micro computer" is intentionally vague, as I have several in mind. Assume each has a TTL input port. Related problems: where find a bar code wand? how to build a bar code wand? can an HP bar code wand be attached to any old micro? where do you locate an HP wand (and specs)??? More Related problems: software! I've found articles in BYTE that describe algorithms for reading bar codes. They appear to be specific to the PaperBYTE (tm) system that was used a few years back. Does anyone still use this format? What about the bar codes on packages (UPC), aren't they a different format? What is 5-of-9, and all they others? Where can I find definitions of all these formats, and *why are there so many*!? tim ("I'm so confused!") born ...ihnp4!ihlpg!timborn
