As a result, many users have their PiDPs doubling up as file or media servers. In fact, as SimH doesn’t put a lot of strain on the Pi, it is unlikely to struggle with other server tasks. You can switch back to Raspbian any time you like. A number of alternative OSes are available, with more promised soon.

Once you log in, you’re straight into the PDP‑11’s operating system, an early form of UNIX. Otherwise, there are a few hoops to jump through, but nothing too arcane and the steps are well explained. At the time of publication, a one-stop SD card image should be available.

The instructions are in an alpha stage, but they are clear and the switch section is especially detailed. This is tricky, but Oscar has provided jigs that make the alignment of all these components much easier than with the PiDP-8. You’ll need to have some experience in soldering to put this together, the focus being on accurately fitting the switches and LEDs. The PiDP-11 is supplied in kit form and there’s a lot to do. The back panel is provided with different cut-outs to suit your cabling. You can hook up a screen if you wish, use SSH, or go old-school and implement RS-232. Running a special version of the SimH emulator, the Pi accurately handles input and output from the panel. Once built, the PiDP-11 PCB comprises 64 LEDs, two rotary encoders, and an array of switches that connect to the Pi’s GPIO. You even get a key and lock, just like the real thing. A perfect facia and custom-built switchgear complete the package. If not for the one-third scale, you would struggle to tell it apart from the real thing. Released in 1970, the original PDP-11 is the most successful ‘mini’ computer in history, with over 600,000 sold.Īuthor's link: /wgWNTC Remarkable replicaįor this new kit, a painstaking process has resulted in an injection-moulded replica of the original PDP-11’s case. Oscar Vermeulen, an admirer of PDP range, has sold over 2,000 of his PiDP-8 replica: a Raspberry Pi-powered emulator with a fully functional one-third scale front-panel. Both it and the later PDP-11 were not only powerful machines, but also beautifully designed objects.

The launch of Digital’s PDP-8 minicomputer in the 1960s was a defining moment in computing history, laying down the foundations of the hardware and software architectures we use today.
