UniBone - a Linux-to-UNIBUS bridge

[Joerg Hoppe]

Hi guys,

I finished "UniBone" - a Linux-to-UNIBUS bridge, based on the BeagleBone Black.

It is supposed to be a Linux based development platform for PDP-11 device emulation.
At the moment it
- can emulate memory,
- emulate an RL11 controller with 4 RL drives attached,
- contains a simple "hello world" device to control some lamps&switches,
as tutorial for own simulations,
- acts as UNIBUS hardware test adapter.

At VCFE.ch in Zurich we also proved that a simulated PDP-11 CPU on the BeagleBone
can access pyhsical PDP-11 peripherals.

There are some web pages at http://retrocmp.com/projects/unibone

(Sorry for cross-posting, but I was told some people read ONLY this forum.)

As much as I love the PDP-11, the lack of something like this is what prevented me from ever considering having a Unibus PDP-11 in my own home.

If there's ever a Qbus version of this I'm probably going to want several.
