A restored PDP-11/83 with a Mentec M11 processor serves this page via 2.11BSD Unix. The system uses two Q-bus chassis linked by M9404/M9405 adapters, running a native C compiler, TCP/IP networking, and a small HTTP server with a cached webtop sampler updating every 5s.

The CPU complex replaces the original M8190 and memory boards with a single-board M11 combining CPU and onboard RAM. Storage includes RA82 and dual RA92 drives via KDA50 MSCP controllers, MFM disk and RX50 floppies on RQDX3, RL02 pair on RLV12, and TKZ50 tape via Emulex UC07. Networking uses a DEQNA Ethernet controller with the BSD if_qe driver, while serial I/O runs through an M3104 multiplexer.

Boot options include MSCP disk boot and RL02 alternate path. Maintenance features console ODT scripts, backup rotation to TKZ50, and periodic RL02 imaging. The live panel shows kernel and process activity, with browser updates pausing when hidden and a front-end cache reducing repeated requests. Source, assets, and restore instructions are preserved in Git.
