Thanks for the information Clark. I had already found the new documentation, however, it appears that "point_of_sale/posbox/index.html" has gone AWOL. It would of been nice if they would of given some consideration to all the broken external links out there. In particular, I've been going nuts trying to find useful documentation on POSBOX. Sadly I feel like Odoo is purposefully making it difficult for those who don't want to pay for SaaS Odoo.
