BBS software for the PDP 11

I did not expect so much feedback, thanks to everyone who responded. I am still reading over all the replies. I am indeed looking to run the hardware for a extended duration or non stop if I can manage to get a good bbs up and running. Power consumption and heat output is not an issue. The machine is set up in its own climate controlled area where it can be left to run for long periods of time. I am not much of a programmer. I thought about writing my own little dinky bbs in assembly or something, but worried i would not understand how to get information stored in a sane manner on the disks or backup to a common format to tape. If i were to run something under 2.11bsd, i could just dump something to tape with tar, which seems alot easier that writing everything lack the knowledge to do so at them moment. I would like to be able to possible run other tasks on the machine while it is running, i have a couple of terminals attached, so unix looks like it may be the way for me to go. I have a heavy investment in RSX too though, i have all the documentation for it here in large binders, it certainly would be interesting to run it on an os ive not seen much of. Still looking over my options, i will post back after i read over all the replys better. --Devin On Thu, May 18, 2017 at 6:45 PM, Bill Gunshannon via cctalk < cctalk at classiccmp.org> wrote:
