A Versatile PDP-11/70 Emulator
The “Kek” emulator, created by vanheusden starting in 2018, replicates the PDP‑11/70 minicomputer. It can run Unix V5 through V7, BSD 2.11, and supports classic peripherals such as RK05 and DC‑11. The emulator is portable across Linux, BSD, macOS, Windows, and even microcontrollers like the Teensy 4.1 and ESP32.
- ▪The emulator named “Kek” was begun in 2018 by vanheusden to emulate the PDP‑11/70.
- ▪It is capable of running Unix versions 5 to 7, BSD 2.11, and supports hardware devices like RK05, RL02, RP06, RP07, KW11‑L, and DC‑11.
- ▪It can be executed on Linux, BSD, macOS, Windows, as well as on microcontroller platforms such as Teensy 4.1 and ESP32.

A Versatile PDP-11/70 Emulator No comments by: Zoe Skyforest August 3, 2026 Title: Copy Short Link: Copy The PDP-11 was a 16-bit minicomputer that was very influential in its time. That’s what inspired [vanheusden] to start working on an emulator for the machine in 2018, which has since been developed to run on a wide variety of platforms. The emulator, named “Kek,” is quite capable, able to run Unix 5 up to an d including Unix 7 in multi-user mode, along with BSD 2.11 Unix depending on what it’s running on. It also supports classic hardware like RK05, RL02, RP06, and RP07 disks, the KW11-L line time clock, and the DC-11 serial line interface. The emulator can also run on a wide variety of platforms.
