As a starting place, I find wikipedia often has good links...

At the bottom of this page:
http://en.wikipedia.org/wiki/Motorola_6800
is a link to "MC6800 applications manual from 1975- lots of information"
actual link:
http://www.bitsavers.org/pdf/motorola/M6800applMan_Mar75.pdf

This is a 36 meg pdf file.  Chapter five has "scanning wand for 
capturing data from printed symbols" and includes the example of UPC 
reading.

The entire document is an image scan so text searching does not work.
