A Versatile PDP-11/70 Emulator

8 hours ago

The PDP-11 was a highly influential 16-bit minicomputer.
[vanheusden] started developing the 'Kek' emulator for the PDP-11 in 2018.
Kek can run Unix 5 through Unix 7 in multi-user mode and BSD 2.11 Unix.
It supports classic hardware like RK05, RL02, RP06, RP07 disks, KW11-L clock, and DC-11 serial interface.
The emulator runs on Linux, BSD, MacOS, Windows, and even on microcontrollers like Teensy 4.1 or ESP32.
Modern microcontrollers are powerful enough to emulate a PDP-11/70 without challenge.
Bob Supnik's SIMH emulator has been doing similar work for over 30 years, but does not target baremetal ESP32 or Teensy.
SpriteTM's esppdp is a port of SIMH for ESP32, supporting a small screen, keyboard, and WiFi.
The text invites comparison between the Kek and esppdp emulators.

Created a weekend device using e-paper screen, physical keyboard, and Raspberry Pi for distraction-free chatting.
Beeper's integration with 15+ chat networks and Matrix-based hackability enabled the project.
Beepberry is an open-source, portable computing device with high-contrast e-paper display, tactile keyboard/touchpad, and RP2040 controller.

YSERVER, a modern X11 server written in Rust with AI assistance, has released version 1.3.
Recent additions include FreeBSD support, Xinerama extension, direct mode VT switching, display hotplug, and more X11 extensions.
Compatible with desktop environments like MATE, Xfce, and Cinnamon, and window managers such as Compiz, Openbox, and Awesome.

Kiln is a desktop app for batch converting, resizing, compressing, and renaming images.
It supports Windows (beta), Linux (beta), and macOS (coming soon).
Users can create reusable pipelines with operations like resize, convert, watermark, and more, in any order.

Chipify is an EDA tool for mismatch simulations, parameter sweeping, and yield analysis.
It automates Monte-Carlo and corner sweeps using Xschem and Ngspice with parallel execution.
The tool provides a PySide6 desktop GUI, a headless CLI, and a plugin system for customization.

Porting an operating system is a complex task requiring infrastructure such as compilers, debuggers, and libraries.
Digital's Alpha Migration Tools Group ported Linux to the DEC Alpha with goals: free, resource-efficient, high performance, source compatibility, and fast schedule.
Initial port used Linux 1.0 code base, 32-bit implementation, existing Digital Unix PALcode and SRM firmware.
