Pico_1140
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 · GitHub 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 SparkFun Thing Plus - RP2040 - SparkFun Electronics. 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 driver for SD card on Raspberry Pi Pico · GitHub) which is included in the repo. The project environment is for Visual Studio Code. The Pico SDK is also required GitHub - raspberrypi/pico-sdk · GitHub. This is not included.
