About, oh say 12 -15 years ago, Motorola published a big thick book of 6800
{yeah - 6800 - only two zeros!} applications information.  One of the
applicatiuons was a bar-code reader.  All the details were there, including a
rundown on several (3?) different bar-code schemes.  The title was something
like "Motorola 6800 Microprocessor Applications" or something like that.  If
you need more information, send me e-mail and I'll try to find the actual
book for the correct title and any other information.  It's probably out
of print, but I'd be it's on microfiche.
