HP-75D Barcode

[Paul Berger (Canada)]

The two codes provided in the pod seem to be odd choices, I have never found anything that uses those codes, however the AT&T logoed pods might explain the code 11 as it apparently is common in the telecommunications industry. The bar code ROM adds some more useful codes the main one being UPC and I have also found tickets that are encoded with INT25 which is also on the barcode ROM. What I did is when I encountered a code I did not recognize I tried the different formats one by one until I hit one that would read.
