KEK

Kek is a DEC PDP-11 (11/70) emulator capable of running UNIX-v6.

To build for e.g. linux:

mkdir build
cd build
cmake ..
make

Required:
* libncursesw5-dev

To build for e.g. windows:

mkdir build-win32
cd build-win32
cmake -DCMAKE_TOOLCHAIN_FILE=../mingw64.cmake ..
make

To run a disk image:

./kek -R filename.rk -b 2> /dev/null

Kek emulates an RK05.

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

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.
