Version 6.0

The source code for the version of DtCyber documented in these pages is maintained here on GitHub . It is built and tested regularly on these host platforms:

• Windows (10 & 11, 32-bit and 64-bit)
• MacOS
• Linux (32-bit and 64-bit)
• RaspbianOS[linux] (ARM-64 and ARM-64A)

Updated: 2025 Dec 28

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 enhanced the simulator significantly by adding emulation of devices such as:

• CDCNet MDI
• PLATO NIU
• 6671 Mux
• StorageTek Tape Library
• Cray Station FEI
• 885-42 DEMA disks
• 885 Large Sector mode
• and more

Kevin's repository also includes support for data communication features such as:

• RJE (HASP, Reverse HASP, and MODE4)
• NJE
• LIP (host-host trunks)
• CDCNet TCP/IP Gateway

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.

Furthermore, Kevin has added support for CYBER 180 class machines supporting NOS/VE in dual-state mode.
