Hello!

I also built the PiDP11/70 Replica a few weeks ago and it worked great. Starting OS could be RT-11 or 2.11 BSD. Should be the easiest OS to start
with.

Greetings, travelers.

I'm building PDP-11 scaled down replica using PiDP-11 kit, which eventually will be able to run multiple OS (emulted by simh) back from
the days - from RT-11 to Unix v7 to BSD 2.x.
Does anyone here had real expirience with the PDP-11 machines and can suggest good starting OS?
Any sugggestions are welcome as well as any docs/refrences/etc :)

I also added two real serials to the maschine and connected a VT420 Terminal. So cool.

Playing Adventure or MTREK on an original Terminal is kind of cool.

Regards
Andreas

I also built one some time ago, along with the PiDP-8. They are beautiful replicas and a joy to work with.

The OSes that come with it are pretty interesting, but the DEC and DEC-like ones are quite... unique from a modern perspective. You can see the evolution from OS8 to RT-11 to VMS to CP/M to MS-DOS, with the early ones being
primitive shades of what we have now.

How was the build? I've been tempted to get one of those for my office. One
of the first "real" computers I worked on in college was an 11/70.


... Courage!
