KEK
Kek is a DEC PDP-11 (11/70) emulator capable of running UNIX-v7.
To build for e.g. linux:
mkdir build
cd build
cmake ..
make
Required:
* libncursesw5-dev
* libjansson-dev
To build for e.g. windows:
mkdir build-win32
cd build-win32
cmake -DCMAKE_TOOLCHAIN_FILE=../mingw64.cmake ..
make
To run an RK05 disk image:
./kek -R filename.rk -b 2> /dev/null
To run an RL02 disk image:
./kek -r filename.rk -b 2> /dev/null
To run a tape image:
./kek -T filename.bin -b 2> /dev/null
ESP32
The ESP32 version needs platformio to be build.
cd ESP32
pio run -t upload
That should build & upload it to a connected ESP32.
Wiring of SDCARD (or use disk-images exported via NBD over wifi using nbdkit (because of older NBD protocol implementation)):
- MISO: 19
- MOSI: 23
- SCK : 18
- SS : 5
- and of course connect VCC/GND of the SD-card
Wiring of the MAX232 connection:
- TX : 17
- RX : 16 Note that you need to use different pins for the MAX232 connection when you want to use the PSRAM of the ESP32.
Raspberry PI PICO / RP2040
Wiring of SDCARD:
- MISO: 16
- MOSI: 19
- SCK : 18
- SS : 17
- and of course connect VCC/GND of the SD-card
The RP2040 version needs platformio to be build.
cd RP2040
pio run
Then copy RP2040/.pio/build/BUILD_FOR_RP2040/firmware.uf2 to the PICO.
SHA2017-badge
This procedure will remove the default micropython environment. Maybe you can undo that, but I have not tried that.
-
esptool.py erase_flash
-
pio run -e SHA2017-badge
-
esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x1000 ./.pio/build/ESP32-wemos/bootloader.bin
-
pio run -e SHA2017-badge -t upload
After this, you can connect a serial terminal to /dev/ttyUSB0 at 115k2 bps.

thanks
Thanks a lot to Neil Webber for his help and for his python PDP emulator (which allowed me to compare disassembly of runs). Neil's emulator can be found at https://github.com/outofmbufs/python-pdp11-emulator
