This page displays screen shots of "FEPSim" - a Front End Processor simulator used for testing by developers.
Unfortunately, the FEPSim UI was not developed to the extent that I would have liked. Instead, I was instructed to focus my efforts on the [very complex] communications protocol that it needed to simulate in order to help other developers get their projects completed. The screen shots here don't do it justice. Under the hood, FEPSim is an advanced C++ software project that implements a complex shared-bus packet-based asynchronous communication protocol, which utilizes a 112-bit encryption based validation scheme - wicked fun stuff!!!
