In 2002 I joined Quest Retail technology as the Hardware design Engineer responsible for the development and release to manufacturing of the VTouch Point of Sale Terminal (POS). The VTouch was a Renesas H8S2633 controller using 1024 x 768 tft lcd touch screen with an Epson graphics and Cirrus Logic ethernet controllers. The product was incredibly successful with large stadiums needing high reliability and low ongoing costs.
The processing power of the H8S was capable of running TCP/IP allowing the POS terminals to be networked over ethernet and WiFi. I developed TCP/IP firmware for configuring and upgrading terminals over ethernet making stadium upgrades a simple remote operation.
