README.md

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

Run: make all to build.

Required:

  • libncursesw5-dev

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

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
