The project
Section titled “The project”QUniLator began as QUniBone, designed and built by Jörg Hoppe — the hardware, the PRU bus logic, the emulation framework and the original documentation on retrocmp.com. Both cards are his design, and his copyright is retained throughout.
The QUniBone/QUniLator repository is
the community-maintained mainline. Jörg’s original reference codebase is preserved
at QUniBone/QUniBoneClassic.
Device emulations contributed by others include the RK11/RK05 subsystem, the MSCP disk subsystem, the RS11/RF11 DECdisk and the KE11 EAE, all by Josh Dersch, and the PDP-11/20 processor emulation by Angelo Papenhoff.
The KiCad symbol for the quad Flip-Chip card came from Malcolm at avitech.com.au.
How the software is maintained
Section titled “How the software is maintained”The code in the QUniLator repository is written and maintained by AI agents. The maintainer directs and reviews the work; the code itself is largely agent-authored. This is the ongoing method rather than a one-off experiment, and it is stated plainly so that anyone who would rather not run software produced that way can make that choice — Jörg’s original codebase remains available at QUniBoneClassic.
Photographs
Section titled “Photographs”Every photograph on this site is by Jörg Hoppe, from the UniBone and QBone articles on retrocmp.com, used with permission.
The oscilloscope traces of bus ringing and its correction are from DEC’s UNIBUS Troubleshooting manual, via bitsavers.

Section titled “Licence”Hardware and software are both BSD 2-Clause. You may forward, modify and sell any of it, as long as the copyright notice remains visible. There is no warranty of any kind.

Sources
Section titled “Sources”Much of this manual descends from Jörg’s original articles:
Pages describing the software as it is now have been rewritten rather than
migrated: the originals document the demo menu application, which the web
interface has since replaced. Pages about the hardware, the buses and the machines
are closer to the originals, because that material has not changed.
Thanks are also owed to the QBUS information page, without which the backplane geometry documentation would not exist.
