Chris,
You are right, the G2 is EOL and we have been supplying 7-Eleven with G3 products for the last several years.
DIGIOP will be happy to discuss your options if you would like to contact us. There are multiple parts to this discussion, but in general there is hardware and software. As for the hardware like many manufacturers the original 7-Eleven unit was launched in 2004 and has gone through many changes. In addition, the software is both VMS and POS integration specific to 7-Elevens requirements. Depending on the need, which would require a discussion we could handle this several different ways. Feel free to contact us at sales@digiop.com or 800-968-3606.
Thanks
Rich
