A PDP11/40 emulator that will run Unix v5/v6 and a number of DEC operating systems.
Introduction and acknowledgements:
This is an updated version of Dave Cheney’s CPP11 GitHub - davecheney/cpp11: Yet another port of my PDP11 simulator which will run on a Pi Pico. For this project I have selected the Sparkfun Thing Plus board which contains an RP2040 chip, an SD card and 16Mb flash. See https://www.sparkfun.com/products/17745. Other hardware may be used including a Pi Pico itself. Wire the SDCard as per the Sparkfun schematic. The SD card interface uses Karl Kugler’s app (GitHub - carlk3/no-OS-FatFS-SD-SPI-RPi-Pico: A FAT filesystem with SPI and SDIO drivers for SD card on Raspberry Pi Pico) which is included in the repo. The project environment is for Visual Studio Code. The Pico SDK is also required GitHub - raspberrypi/pico-sdk. This is not included.
