AXPbox is a fork of the discontinued es40 emulator. It could theoretically used for running any operating system that runs on the OpenVMS or Tru64 PALcode (e.g. OpenVMS, Tru64 UNIX, Linux, NetBSD), however as of now only OpenVMS and some versions of NetBSD can be installed (for more details see Guest support).
The emulator supports SCSI, IDE, serial ports, Ethernet (using PCAP) and VGA graphics (using SDL).
OpenVMS 8.4 desktop in AXPbox. Here is a wiki page showing you how to get this CDE desktop running
Pre-built binaries for generic Linux amd64, Windows 10 amd64 and macOS amd64 are available for each release, and also as artifacts produced for each commit in CI. T2 SDE has an official package for AXPbox, and openSUSE's Emulators project has an AXPbox package, too. The former gets updated the same day when a release happens, while requests are submitted now the latter that undergo approval of Emulators maintainers.
You can also build from source using CMake; you need a C++ 11 compiler, optional dependencies are PCAP for networking and SDL or X11 for graphics support.
First invoke the interactive configuration file generator:
axpbox configure
This creates a file named es40.cfg, which you can now modify (the generator UI doesn't allow to set all options). After the configuration file and the required ROM image are ready, you can start the emulation:
axpbox run
Please read the Installation Guide for information to get OpenVMS installed in the emulator. A guide for NetBSD is also available on the Wiki
- Renamed from es40 to AXPbox to avoid confusion with the physical machine (AlphaServer ES40)
- CMake is used for compilation instead of autotools
- OpenVMS host support was dropped
- es40 and es40_cfg were merged into one executable (axpbox)
- The code was cleaned to compile without warnings on most compilers
- Code modernizing, replacing POCO framework parts by native C++ counterparts not available in 2008 (std::threads, etc)
- Incorporate various patches from other es40 forks, for example, added MC146818 periodic interrupt to allow netbsd to boot and install, skip_memtest for faster booting.
- Bug fixes, less segfaults, overall less crashes.
- More documentation and usage information on the various features and operating systems
- Some guest operating systems (see Guest support)
- ARC
- VGA in OpenVMS
- SDL keyboard (partly works, but easily breaks)
- Multiple CPU system emulation
- Running on big endian platforms
- Some SCSI and IDE commands
- Networking for a longer time (breaks after a couple minutes)
- Copying large files between IDE CD-ROM to IDE hard drive (this usually doesn't affect OpenVMS installation)
