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 :)

RSX-11M-PLUS and RSTS are the best "native" OS available on PDPs, IMHO.
Unix was born on a PDP, so I think that V7 can be also a nice choice. :)

I'm running a SIMH PDP11/93 with RSX-11M-PLUS V4.6 with free login on Internet if you want go a walk through.
It runs the TCP/IP stack developed (and still fully maintained) by Johnny Billquist.

Oh, that's nice! I'll give it a try (actially, already did), but guess need to read some manuals first as I couldn't make it beyond 'dir' :^)

Thanks a lot! This a pretty good starting point, will keep digging from there...

Ah, so you won't mind if I bother you time to time when I'll come to running my rig, not just soldering it, would you?

Cool!

No sorry ... I am too young for experience with the Dec PDPs.

But I would be very interested in your comments.
I was thinking about it, but I have too little attachment to the PDP and it was too costly for me.

I have the KIM Uno and like it very much ;)

Re: PDP-11 OS expirience

Not experience with the real thing, but BSD 2.11 is the most complete Unix experience
you can get from such deployment in my opinion. It has the tools we all know and love.

It makes one think thinks through when you realize tools we use on Linux and modern
BSDs were already in use back then.

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.

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.

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.
