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 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 See SHA2017-badge.md if you want to flash your SHA20127 badge with this software.
