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

When you run UNIX 7, you can (if your system has enough RAM - use an ESP32 with 2 MB PSRAM or more) run multi-user via the DC-11 emulation. Note that UNIX 7 starts in single user mode first; press ctrl+d to switch to multi user (recognizable by the login-prompt). Also make sure to configure networking ('startnet') to be able to connect (using telnet) to the DC-11 ports (TCP port 1101 upto and including 1104).

ESP32

The ESP32 version needs platformio to be build.

cd ESP32
pio run -t upload
pio run -t uploadfs

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

Heart beat LED:

  • pin 25

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
