Kevin Jordan's repository of the dtCyber codebase is one of the most complete and best-maintained after Tom Hunter's retirement from the project. Kevin has done a terrific job of enhancing the simulator and has added emulation of devices such as MDI, PLATO NIU, 6671 Mux, StorageTek Tape Library functionality, Cray Station FEI, and more. It also includes support for data communication features such as RJE (HASP, Reverse HASP, and MODE4), NJE, LIP (host-host trunks), CDCNet TCP/IP Gateway, etc., it provides browser-based emulators of ANSI X3.64 (aka VT100), Tektronix 401x, Pterm, and IBM 3270 terminals, and it provides browser-based (both 2d and 3d) Cyber console emulation too.

Steve Zoppi's repository is a fork of the Jordan repository and all features are built upon Kevin's work.
