"Burroughs software was designed to run only on proprietary hardware. For this reason, Burroughs was free to distribute the source code of all software it sold, including the MCP, which was designed with this openness in mind. "
You can download an official emulator from their website. It’s proprietary and runs on Windows, and you have to sign a license promising you’ll only use it for development.
But I have to warn you: It is one of the most user hostile OSs I’ve have ever seen.
If anyone thinks vi or Emacs are hard, they should play with CANDE.
Part of the technical school tranship was on OS/400 state of the art in early 1990's doing system backups to tapes, I also did my typing exam for computing in PCs running MS-DOS 3.3 with edlin, I think CANDE is manageable. :)
CANDE is not software you use. It's software you fight and submit to your will. It's a bit like Emacs, but made by people with 4-digit IQs, for people with 4-digit IQs.
Unisys has been very supportive of our efforts to find and preserve early Burroughs software and generously provided corporate time to arrange licensing and provide copies of anything they still had.
Burroughs B5000 series now has a rich library of software and several emulator implementations (web-browser, simh and standalone). However the B6000/7000 family software recovery is sparse with critical pieces still missing, we are unable to bootstrap a working MCP as yet.
Nice to know, navigating the site to get stuff like the latest NEWP manuals, the new Web interface and other similar stuff, seems to have moved into "talk to sales" kind of stuff, so hence why I was wondering that.
