A restored PDP-11/83 serving this page on 211BSD Unix
summary
This system is a restored PDP-11/83 that combines vintage hardware with modern updates like the Mentec M11 processor to maintain operationality. It runs 2.11BSD UNIX, providing a networking stack and a small HTTP server to share its status live. The setup preserves 16-bit computing history by integrating a mix of DEC and Emulex controllers for diverse storage media. This integration allows the system to serve as both a functional machine and a digital archive.
key points
- The hardware architecture uses a Q-bus system across two chassis, integrating a variety of storage controllers including RQDX3, UC07, and KDA50 to support MFM disks, SCSI, and tape drives. This ensures compatibility with legacy media like RA82 and RX50 drives.
- The software stack is powered by 2.11BSD, which enables native C compilation and TCP/IP networking. This allows the system to actually host a website and provide real-time system snapshots via a tool called TMOG-11.
- Maintenance is handled through a combination of MSCP disk booting, periodic imaging of RL02 drives, and the use of Console ODT scripts for diagnostics. This ensures the long-term reliability of the long-term reliability of the system's physical components.

Computing historians and vintage hardware enthusiasts who want to see how 16-bit UNIX systems are integrated with modern components for preservation.
discussion skeptical
consensus
Commenters are deeply divided between admiring the technical feat of restoring a PDP-11 and expressing strong skepticism toward the creator, Dave Plummer. While some appreciate the hardware restoration, many criticize the accompanying website for appearing to be AI-generated 'slop' used as a vehicle for advertisements. There is also significant distrust stemming from Plummer's reputation for self-promotion and past business practices.
top insight
The technical debate regarding the DEQNA network interface reveals that while connecting vintage hardware to modern networks is challenging, it is feasible via NetBSD support or UTP transceivers. This provides a practical counterpoint to the skepticism, suggesting the project's hardware claims are technically possible even if the presentation is off-putting. The discussion shifts the focus from the 'AI look' of the site to the actual engineering requirements of 211BSD Unix on a Q-Bus system.
